Save the graphs obtained by simulating both circuits and answer the following
questions in your report:
o Do you observe a difference in both graphs? If yes, explain why is it
happening?
o Measure the peak values of both the input and output signals obtained by
simulating the circuit in figure 3A_1. Do you see a difference between peak
values? Explain why does it occur?
o The phenomenon that you have just witnessed is known as rectification.
Could you explain why this particular case is referred to as half wave
rectification?
o Now change the frequency from 1K Hz to 10K Hz and observe the difference.
Why do you think the graph has now changed? Explain.

happening?

o Measure the peak values of both the input and output signals obtained by

simulating the circuit in figure 3A_1. Do you see a difference between peak values? Explain why does it occur?

o The phenomenon that you have just witnessed is known as rectification.

Could you explain why this particular case is referred to as half wave rectification?

o Now change the frequency from 1K Hz to 10K Hz and observe the difference.

Procedure

Set up the circuits given in fig-3B. Apply 10 volt peak to peak sine wave as an input signal and see the output signal across the 1K Resistor, on oscilloscope for both the circuits.

Observations/Measurements:

  • Observe the Input and output waveforms on a dual trace oscilloscope.What differences are observed between input and output waveforms and why?
  • If we were to use two diodes in series, how would that affect the output of the circuit? Explain.
  • Also, change the frequency of the input and observe the difference in the waveform. Why do you think it has changed?
