In a certain communications system a resonant-tuned circuit (tuned at 1200 kHz with Bandwidth = 15 kHz) is connected to the output of a non-linear amplifier (mixer). Find the frequency components at the output of the resonant-tuned circuit?
Calculating peak frequency deviation and Carson's rule bandwidth, A baseband signal has a frequency range from 50 Hz to 15.0 kHz. The signal is transmitted using frequency modulation. The FM transmitter has a modulation constant of 100 kHz per vol..
The outputs of two "NAND" gates are connected to the inputs of an "Exclusive Or" gate. Each of the "NAND" gates has one input at a logic high level, and the other input at a logic low level. What is the output of the "Exclusive Or" gate?
a. Describe the operation of a typical NMOSFET transistor used both as an amplifier and a switch. b. List the 3 regions of operation and draw the I-V characteristic curve. c. Show the effect of channel length modulation on your graph.
1. Sketch the polar plot of the frequency response for the following loop transfer functions: Gc(s)G(s) = 1 / ((1 + 0.25s)(1 + 3s)) Gc(s)G(s) = 5(s^2 + 1.4s + 1) / (s - 1)^2 Gc(s)G(s) = (s - 8) / (s^2 + 6s + 8) Gc(s)G(s) = 20(s + 8) / (s(s +2)(s + 2)..

What is the bandwidth occupied by this signal, and the noise bandwidth of the receiver for this signal? Find the BER at the receiver output and the average time between errors.
A Si sample is doped with 10^17 As atoms/cm^3. What is the equilibrium hole concentration P0 at T=300K?
Bipolar Junction Transistor, A silicon n-p-n bipolar junction transistor is designed with emitter, base and collector doping levels of 10^19cm, 10^15cm and 5*10^17cm, respectively.
Binary symmetric channel, Assume that we are transmitting binary digits over a binary symmetric channel. Let p(x=0)=p(x=1)=0.5.
transfer function: T(s)=1/(0.1s+1) with all initail conditions at 0 a) if the input is 1.5sin(2t)*u(t) find the steady state value of the output b) after the input is applied, approximately how long will it take for the steady state value you found i..
Linearity, order, casuality, and time variance for systems, What are the linearity, order, casuality, and time variance of each input-output relationship for systems?
You do some quick measurements and find that the area of the lagoon behind the dam would be about 5m wide by 20m long, and the lagoon would be about 3m deep at high tide, and 1m deep at low tide.
