Joshua Dean ECE 3220 PRELAB 15 3-20-2011 80/100 1.4 Sampling and Aliasing Demo In the pre-Lab, you should perform the following steps with the con2dis GUI: (a) Set the input to x(t) = cos(40_t) (b) Set the sampling rate to f s = 24 samples/sec. (c) Determine the locations of the spectrum lines for the discrete-time signal, x[n], found in the middle panels. Click the Radian button to change the axis to from ˆ f to ˆ!. [-10] What are the locations of the spectral lines? (d) Determine the formula for the output signal, y(t) shown in the rightmost panels. What is the output frequency in Hz? The output frequency is 4Hz .

Joshua Dean ECE 3220 PRELAB 15 3-20-2011 1.5 Discrete-Time Convolution Dem In the pre-lab, you should perform the following steps with the dconvdemo GUI. (a) Click on the Get x[n] button and set the input to a finite-length pulse: x[n] = (u[n] − u[n − 10]). (b) Set the filter to a three-point averager by using the Get h[n] button to create the correct impulse response for the three-point averager. Remember that the impulse response is identical to the b
