In a RC circuit with input Vi(ω) and output Vo(ω)
1. Calculate Vo( ω)/Vi(ω) for R=5KOhm. What is the frequency when Vo(ω)/Vi(ω) =-3 dB and what is the frequency when Vo(ω)/Vi(ω) = -20 dB?a. 6.64 KHz and 66.4 KHzb. 9.95 KHz and 99.5 KHzc. 19.9 KHz and 199 KHzd. None of the above; see Problem Work
2. The output response for a system is given as Vo(t) = A(1-e^-at)sin(ωt). Is this a proper representation for an output response given that it contains a sinusoidal term? Fully explain your answer.
Consider an 8-user CDMA system. The data vector of all users is given by [1,1,1,1,-1,-1,-1,1]. Find the total transmit signal.
the circuit has been connected for several seconds, find current in (a). in the 4.00 volts battery, (b). in the 3.00 ohm resistor, (c). in the 8.00 volts battery, (d). in the 3.00 volts battery and (e). find the charge on the capacitor?

You want to download a 5 Mbit file over a 10-Mbps Rayleigh fading channel in the 1800 MHz frequency band. You are traveling at 6 km/h and use 1000-bit packets.
Improve the controller designed in part by introducing a mechanism for the disturbance compensation at the plant input. Illustrate advantage of the improved controller by applying the fast varying piecewise constant reference input vector and sinu..
Calculate the S/N ratio for a receiver output of 4 V signal and 0.48 V noise both as a ratio and in decibel form. (69.44, 18.42dB)
The angle of departure is defined as 180 degrees plus the phase angle of GH computed at the complex pole, but ignoring the contribution of that particular pole.
Can you confirm-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 logic high level and the other input
