Telecommunications Definition and 29 Threads

In telecommunication system there's a fresnel zone, it's an area between transmitter and receiver (i'm sure all the experts in this forum already knew about that). So, in this website (Fresnel Zone Calculator - everything RF) provide a Fresnel Zone Calculator, it also tells the equation, which...

I'm stuck on this because v is a 2 tone signal, so it's not as simple as Am/Ac. The teacher said I will need to differentiate it and equate it to zero, which I thought made sense. Differentiating v gives me: [- mwsin(wt) - mwsin(2w*t)], so there's still unknown variables. I don't know how I'm...

I'm an undergraduate EE student, the last few semesters I have been taking courses in telecommunications. I took an introduction to telecommunications course, a course on data communications, and a course on digital communications. I have not taken a course on wireless communications and will...

Summary:: Looking for a title and an idea to do a research project on the topic of satellite communications Hello fellow FP, I am in desperate need for an idea to do a project, seminar, call it what you like, on the topic of satellite communications for a course. We covered the basics of...

Summary

How did you find PF?: Google search I got a problem, how to calculate this formula from euler to imajiner? or how calculate this case?

Hi PF! I am interested to know whether there are applications of holography in telecommunications, and if there is research on this topic. If there is some literature on this topic (provided holography is used in computer networking) where I can read and learn more in-depth about this topic, I...

If we have 300kHz bandwidth and every channel uses 100kHz BW, then theoretically we can have total of 3 channels that won't overlap. Why do we need to assign some of the bandwidth for "safe gap" between channels if they "don’t" overlap?

I am very confused with the 3G, 4G, LTE, UTMS, WCDMA terms... Hope someone could shed some light on it. I think complication arises when marketing people start to use these terms interchangeably? Below is my interpretation, is that correct? Would someone be kind enough to make some comments...

Hello everybody, I'm a little bit confused about two types of amplitude modulation. We distinguish here: Case I : Amplitude Modulation with suppressed carrier (https://en.wikipedia.org/wiki/Double-sideband_suppressed-carrier_transmission): Case II : Amplitude modulation with carrier: Now...

1) I am studying modulation of carrier waves, but I still can't understand something: knowing that in AM the carrier wave has only one frequency and just only its amplitudes vary according to variations in modulating signal amplitudes, why AM carrier waves have bandwidth if the frequency is...

How telecommunications work? I mean, there are so much waves around us nowadays, how my cellphone recognizes a single signal and rings only when it detects it? If my cellphone is a receipter, why can't I listen to my neighbor converstation, why isn't there a lot of interference and how waves...

1) I understood how variations in the amplitude of modulating signals are represented in the carrier wave, but I didn't get how frequency variations of the modulating signal are represented, as both AM and FM modulations seem do not care about it. Ex: How to distinguish a high vocal range (high...

Does SNR give a clue to bandwidth limitations? i. e. Would it help to figure out how the signal is distorted due to the limitation of the bandwidth? I think answer is "no" though.

Here is my task (Basics of analogue telecommunications): Block diagram of device for simultaneous transfer of two telegraphic signals u1(t) and u2(t) is shown on image 1. Both signals have waveform as periodioc signal um(t) on image 2. Frequencies f1 and f2 of carriers $$u_{01}(t)=U_0...

Halo! I hope to graduate from college of engineering where I study Bachelor of science Electronics and Telecommunications engineering before graduating I required to do a project on my field Help me with a title of which best project I can do. Thank you in advance

I'm a historian. I've struck on a curiosity about telecommunication technology in pre-modern times. I've read about a number of methods, and I'd like to ask some physics questions that got beyond my ken. This information is for my curiosity and creativity, not for any rigorous study, so I may be...

Hello, I'm Community Growth Manager at OpenSignal. Studied pure mathematics for my bachelor's degree, but never got around to going deeper with physics. Now that I'm in the mobile sensors, electronics, and wireless communications / telco space, I am extremely interested in everything connected...

I am not referring to solar winds, just normal adverse atmospheric conditions. Thank you Regards

Homework Statement draw the eye diagram you would expect to see should a digital signal be passed through a transmission line with a bandwidth limited to three times the maximum bit rate of the digital signal. the answer is "Only f1 and f3 pass through" My question is, what about f2 ? Why...

Hello, I have just started reading some telecommunications basic concepts. I have a question regarding the following phrase: "when considering that transmission lines are used in transmitting AC signals: R << ωL G << ωC In high frequency applications the R is so much smaller than the xL...

I am trying to design a tone generator similar to those used in telecommunications applications (ex: http://www.tessco.com/products/displayProductInfo.do?sku=89724&eventPage=1) The probe (inductive amplifier) can be used on any tone generator, so I plan to use it with mine. So far, I have...

Would anyone kindly tell me, in a bit detail, the applications/usefulness of Quantum Mechanics in the field of Telecommunications Engineering? I'd be thankful.

Hi Guys, First off i'd like to say what a site! having found it over the weekend it's given me hope that there may well be hope for me yet. I'm in Ireland and in first year of a BSc in Computer Network Administration, it's a new course and I am a returning mature student, it's about the...

can anyone explain this major for me ( telecommunication managament ) ? thanx in advance

Why/how does weather affect telecommunications? The photons in radio waves can pass through matter, such as human bodies and concrete, but they seem to be affected by weather conditions. Why is this, or is my reasoning flawed?

our physics teacher said that de broglie waves was widely used to explain a lot of outstanding phenomena like noumenal telecommunications,even i read by applying the quantum mechanics to the brain matter we can explain thinking and thoughts as resonances in our brain even we can explain feelins...
