1) Here it is again, our favorite signal: the sinusoid. V(our friend) volts 4V-T 3V- 2V- 1V- ev- -1V- -2V- -3V- -4V- 0 Frequency: Hz 0.001 Amplitude: volts Period: 0.002 seconds seconds a) We wish to digitize this signal. What is the minimum sampling frequency necessary? Hz b) What happens if the sampling frequency is too low? Be specific ("damage" is not a good answer). c) What is the input voltage range this quantizer can measure properly? volts d) Based on your answers above, what undesirable result will be obtained if we try to use this quantizer to digitize our sinusoid?
