5-1- The output sequence signal and the sampling rate of an ideal C-to-D converter is shown below. If the input wave x(t) is given by the two sided spectrum representation shown below determine the spectrum for x[n] when sampling frequency is 2500 samples/second. Make a plot for your answer (versus discretetime (or digital) frequency) showing the frequency, amplitude and phase of each spectral component. answer: 4-2- To synthesize a continuous-time signal, the assumption was that all of its spectrum components were added together. Is this true for discrete-time signals? Explain your answer by highlighting the reasons for displaying several different frequencies in representation of DT signal spectrum. Solution : No, a discrete time signal spectrum components cannot be added together to synthesize the signal. The reconstruction of a discrete time signal is possible only from it samples. When a discrete signal is sampled at different sampling frequencies, the location of various spectrum components that make up the signal changes.The spectrum
