-1/4, n = -2 -1/2, n = -1 Q1: Find the DTFT of x(n) 1/2, n = 1 Graph the magnitude and the phase of the transform. 1/4, n = 2 0, otherwise

Using Verilog continuous assignments or VHDL signal assignments, write a description of the circuit specified by the following Boolean functions: Out_1=(A+B′)C′(C+D)Out_2=(C′D+BCD+CD′)(A′+B)Out_2= (AB+C)D+B′CWrite a testbench and simulate the circuit’s behavior.

Draw the graph of the NRZ-L, NRZ-I, Manchester scheme, differential Manchesterscheme using each of the following data streams,assuming that the last signa11evel has been positive. From the graphs, guess thebandwidth for this scheme using the average number of changes in the signal level.a. 00000000b. 11111111c. 01010101d. 001100115.

According to Fourier analysis, any composite signal is a combination of sine waves with a. diff frequencies amplitude, and phase b. different frequencies c. same frequencies d. same frequencies with amplitude and phase

157. The term that refers to the phase continues through the boundary of two signal elements is a. non coherent BFSK b. coherent BFSK c. Binary ASK d. Multilevel ASK

Compute the propagation delay in this case.

1.A(n) __________ signal is a signal that can take on any amplitude and iswell-defined at every time. 2. A(n) __________ signal is a signal whose amplitude can take only finite setof values, normally two, and is defined only at a discrete set of times.

Implement MATLAB program that plots channel capacity vs signal to noise ratio for 2-PSK,4-PSK,8-PSK modulations

It is known that an LTI system with the relation between the input signal x(t) and the output signal y(t) is given by the following differential equation: (image) Determine the frequency response of the LTI system above.

Normalize the spectra data set to unity: For X= [0.23, 0.025, 0.54, 0.58, 0.18, 0.64, 0.29, 0.012, 0.72, 0.35] ?
