In radio communications, a radio receiver, also known as a receiver, a wireless or simply a radio, is an electronic device that receives radio waves and converts the information carried by them to a usable form. It is used with an antenna. The antenna intercepts radio waves (electromagnetic waves) and converts them to tiny alternating currents which are applied to the receiver, and the receiver extracts the desired information. The receiver uses electronic filters to separate the desired radio frequency signal from all the other signals picked up by the antenna, an electronic amplifier to increase the power of the signal for further processing, and finally recovers the desired information through demodulation.
Radio receivers are essential components of all systems that use radio. The information produced by the receiver may be in the form of sound, moving images (television), or digital data. A radio receiver may be a separate piece of electronic equipment, or an electronic circuit within another device. The most familiar type of radio receiver for most people is a broadcast radio receiver, which reproduces sound transmitted by radio broadcasting stations, historically the first mass-market radio application. A broadcast receiver is commonly called a "radio". However radio receivers are very widely used in other areas of modern technology, in televisions, cell phones, wireless modems and other components of communications, remote control, and wireless networking systems.
Hello ,
I searched online , but to no luck . can anyone help me with weblinks from where I can get MATLAB codes to design a transmitter and reciever in a communication system . Thanks in advance .

Hi,
Is it possible? I've found quite a few piezo electric transducers on rs.com but I wonder are they only good for transmitting or could they be used as a receiver with a really good pre-amp?
Can anyone tell me? If so will they lose some of their response at low frequencies when used in...
I have a project in one of my classes, the aim of the project is to interface a circuit which you will design with a computer through a USB port, I read a lot about software defined radio's and I was thinking of building a very basic one which will receive AM signals and then convert them...
This is a UART problem, we need to design a counter for the receiver unit. And the specs go like this:
system clock is 20 MHz, while data arival frequency is 2MHz, also I need to assert a STOP_RECEIVING signal once all data is received. And of course, data has a start bit and a stop bit. And...
can someone please post some plans + components list for a VHF AM reciever (or a transciever) Freq range of about 100MHz - 130MHz. Thx in advance. :smile:
I've been looking all over the Internet for what I thought would be an easy thing to find instructions on. Unfortunatley, anything that comes close either complicates the matter with extra features or assumes I know a lot more about electronics than I do...
I need to build a very simple...
our teacher gave us this one in class and its not one of the "regular" ones we do so i same not sure how to set it up w/o getting messy numbers.
2 loud speakers 2.5m apart and a reciever 3m from one speaker and 3.5m from the other.
a. find the lowest frequency where the receiver is a node...
Hello,
How can we convert parallel-to-serial address and send it as an optical signal?
Have a look at the link below if you folks don't know what I mean - the last (3-4 lines) paragraph of the pdf file:

Hi!
I am going to have a science exhibition in the first week of February and our professor has asked us to make a project (that works!). He wants it by mid-January though. Anyway I decided to make a transmitter and a receiver (like a transmitter and a radio). I saw the popular Rough Science...
