Document Summary
As voted on in class, test #3 will be on tuesday 19 april 2016. In addition to the problems from the first two tests, the following problems are candidates for exam questions: given the signal x(t) 1: determine the fourier transform of x(t) both by equation 4. 9 and by using the tables, use the property of duality to find the inverse transform of y(j ) : jy. 1 else: determine the discrete-time fourier transform of the following signals. You may use tables or the transform summation: (1/3)n u[n, (1/3)n u[n-1, for the system y[n] - 1/2y[n-1] = x[n-1] (a) find h(ej ). (b) if x[n] = (1/4)nu[n], what is y[n], a signal is tx cos( 40: what type of modulation is this, draw and fully label |y(jw)|, as part of what type of multiplexing would this be used, for the transfer function sh s. Draw the magnitude of the straight line magnitude bode plot for this transfer function.
