What is the minimum sampling rate needed in order to successfullycapture frequencies up to 80MHz in an analog signal?
Convert each of the following decimal values to 8-bit two’scomplement binary.i) -3810 ii) 5510 iii) -6510 iv) 7210
Generate a single-tone signal whose peak amplitude is 2 V and frequency of 1000 Hz. Use a 20000 Hz sampling rate and a duration of 1 s. Plot the signal for the first 50 points only and observe (listen to) the signal using the wavplay (Note: DO NOT DO THE wavplay COMMAND! It is going to get very noisy in the laboratory. But do include the command in your code.)
