Write a simulation that implements an OQPSK transmitter. Place a bandpass filter on the transmitter output to limit the transmitted signal to the main lobe.
Create two adjacent channels, which are also OQPSK transmitters limited to the main lobe. Place the adjacent channels as close as possible to the desired channel, without allowing the spectra to overlap.
Pass the signals through an AWGN channel, and a matched filter receiver. If the interfering signals are not present, set the BER of the system to 10-3. Use MC simulation to estimate the BER when the interfering signals are equal in power to the desired signal.
A radar transmits a monotone pulse of 5-s duration. Suppose the radar were redesigned so that the same pulse envelope is frequency modulated with linear FM over 100 MHz. (a) What is the possible new range resolution
The propagating pulse passes an observer at x=0. The peak of the pulse can be approximated by a parabola, v(t)=20 (1 - 10t^2), where v is the mV and t is in ms. (a) find the current along at x=0, t=0 (b) find the membrane current per unit area at ..

Visit the appropriate material and show me the contrastial fig of the s an p of below as ref. - Be clear and accurate.
What is the function of "junctors" in a switch (e.g., a DMS-100)? To make a switch "universal"-that is, easy to change over from DS1 format to E1 format and vice versa-often internal bit rates were also based on an X/Y ratio between DS1 and E1. Wh..
What is the purpose of administering a pretest?
A maintenance firm has gathered the following information regarding the failure mechanisms for air conditioning systems:The units without evidence of gas leaks or electrical failure showed other types of failure. If this is a representative sample o..
a motorcycle battery delivers around 10 Volts DC, at an ampacity of about 500 Amps. this voltage goes through ignition (transformer) and it delivers about 30 KV to each spark plug. What is the turn ratio (Ns/Np) and the resulting ampacity on secon..
Given the following next state and output equations for a synchronous sequential circuit:a. Construct the transition table (state table) for the circuit showing present states, next states and outputs. b. Draw a state graph for the circuit.
