A receiver with a synchronous detector receives a barely intelligible message since the (s/n)d =4 db . it has been determined that the transmitter has ST= 100 W , μ = 0.9 and SX=0.5. What is the
A certain internally compensated (dominant pole) op amp has a dc gain of 200,000 and 3 dB bandwidth of 5 Hz. Sketch the Bode plot of the magnitude of the open loop gain to scale.
A certain inverting amplifier has a closed-loop gain of 25. The op-amp has a open-loop gain of 100,000. If another op-amp with an open loop gain of 200,000 is substituted in the configuration, find

a.) Plot x[n] as a function of n and use the definition of the z - transform to find x[z]. b.) Use the z - transform of u[n] and properties of the z - transform to find x[z]. Verify that the express
Inverse Z-transform and poles and zeros. When finding the inverse Z-transform of functions with z-1 terms in the numerator, the fact that z-1 can be thought of as a delay operator can be used to sim
Consider the inverse relation given by z=eSTs - that is, how to map the z-plane into the s-plane. a.) Find an expression for s in terms of z from the relation z = STs. b.) Consider the mapping of the
a.) Determine where the given poles are mapped into the z-plane.b.) How would you determine if these poles are mapped inside, on, or outside the unit circle in the z-plane. Explain.
How can one determine whether a given signal is real-valued or complex valued from the Fourier series coefficients 1) A signal with a fundamental period of 12, and a5=1, a6=1 (rest are zeros)
Given one has frequency response of a system (magnitude and phase), and a sine wave of a given frequency and phase is input, explain how to find the output.
which electrical meters are self-powered from an internal source such as a battery, and which meters draw their power frm the circuit to which they are attached
Sometimes the partial fraction expansion is not neede in finding the inverse Z-transform -instead the properties of the transform can be used. Consider the function F(z)= (z+1)/z^2*(z-1)
When no real time processing is needed the system can be noncausal. Consider the case of averaging an input signal x(n) uner real time conditions. suppose you are given two different filters y{n}= 1
Supposed that the signal y(t) is low -pass filtered. The magnitud od the low pass filter is unity and the cut off frequency is Rz= 5000*pi rad/sec. Determine the value of the sampling period Ts acco
Consider an analog periodic sinusoid x(t) = cos (3*pi*t + pi/4) being sampled using a sampling period Ts to obtain the discrete time signal x[n] = x(t)I t=nTs = cos (3*pi*t + pi/4). a.) Determine th
The film is developed with an overall gamma of 2, reinserted in the position of the film during recording and reconstructed using the same point source as that used to construct the hologram. Using
