This is to be done using P-Spice

1. Create a "random signal bandwidth limited to 1kHz using a VPULSE source and LOPASS filter as shown below. D OUT 800 1k 1dB 50dB V1 = 0 V2 = 10 TD = 10u TR = 0 TF = 0 PW = 1ms PER = 15 sillo 2. Run the simulation for 20ms and look at the waveform. Be sure to set the maximum time step small enough (10us). 3. Using a MULT block and another VPULSE source, simulate sampling the waveform at 5kS/sec. Do this by multiplying the random signal by very short duration (10us) unity amplitude pulses at the sampling period. You can set the delay time (TD), rise time (TR) and fall time (TF) to 0. 4. Run the simulation and look at the resulting waveforms. Write a few observations about the waveforms. 5. Look at the FFT of the waveforms. Multiply the output of the multiplication by 10 and compare the spectrums. (You can just double click on the waveform legend and put 10* at the beginning.) Write a few observations about the spectrums of both waveforms. 6. Use an OPAMP voltage follower, a voltage controlled switch (S), and a capacitor to create a sample and hold circuit. Control the switch with the same sampling pulse and use the output of the switch (not the multiplication block) as the input of the opamp. A 1uF capacitor is sufficient. 7. Look at the output waveform in both the time and frequency domain. Write a few observations about the waveforms and spectrums of the waveforms. Sample and Hold in-class Exercise 1.
