I'm getting confused here. Where should the - terminal of oscilloscope and function generator be connected to?
The results of the simulation are shown below. Keep in mind I am supposed to get -10V and 10V
dc
AC
I have the circuit below which is supposed to take input of 100mV to 400mV and output a voltage of -10v and 10V respectively. I have designed the circuit below through multisim and would like to verify if its correct before trying to connect on breadboard. When I simulate the circuit, I get...
ok. I am to design a ckt. where the inputs range from 100mV to 400mV and the output ranges from -10V to 10V. I have attached my workings and a final design of the op amp ckt. Am I on the right track?
For example like this
Input range 100mV to 400mV and output Range is -10V to 10V. And it says design a zero-span ckt,
edit:changed input range from 40mV(mistake) to 400mV
Homework Statement
A non-linear oressure sensor has an input range of 0 to 10 bar and an output range of 0 to 5V. The output voltage at 4 bar is 2.2V. The nonlinearity as a percentage of psan is?

This is a question from a past exam paper I have.
In a communication system the distance between Node A and Node B is 400 km. The distance between Node B and Node C is 1000 km. Frames are generated at Node A and sent to Node C through Node B. Determine the minimum data rate required...
thanks for reply, but I am having tough time understanding this
I read that
each call requires a channel. But in the question below I have 19 channels but 120 users. Isn't that ineffecient as there will be a lot of calls being blocked.
Would not the probability of a call being blocked be...
If a channel is 5Khz for a full duplex system in cellular systems does that mean person A and person B are using the whole 5Khz to communicate?
Or can the channel accommodate a lot of people?
Homework Statement
The solution does not take into account Gain of transmitted antenna. Why?
From friis eqn, Pr(db)= Pt+Gt+Gr-Lp, but soln. omits Gt

Hi
1. Sorry its dbW. I will change to dbm later this is not a issue
2.free space loss formula. Sorry about the writing. So I can find this out by substituting the appropriate values i.e. R is the distance between the 2 antennas and lamda can be caluclated since frequency and speed of light...
thanks for the reply. I've attached a copy of my working out. I stated in my original post that L_p was found, however, it is only the free space loss of two isotropic antennas
Homework Statement
In terrestrial microwave link, line-of-sight transmission limits the separation of transmitters and receivers to about 40km. If a 100mW transmitter at 4GHz is used with transmitting and receiving antennas of 0.5m^2 effective area, what is the received power level in dBm...
This is not a connection. I just want ot know how they dervied this formula from gain
Consider a geosynchronous satellite whose global beam covers all of the visible Earth's surface. The radius of the Earth is about 6400km, and the altitude of the satellite is 36,000km.
How would you work...
