2
Design a regenerative feedback circuit with the hysteresis of
DC transfer characteristics of the system. Estimate the hysteresis and see how
it can be controlled by varying the regenerative feedback
Vary either
the peak voltage of 10V at a given frequency to both circuits and observe the
output waveform.
Notes on Experiment 2:
a)
b)
Submit the simulation results for DC transfer characteristics.
Take the plots of DC transfer characteristics from oscilloscope and
compare it with simulation results.

Design an astable multivibrator using charging and discharging of capacitor
C through resistance R between input and output of the Schmitt trigger. See
Figure 2.4. Assume that frequency
Design a monostable multivibrator for
formula 2.5.
c)
Vary the regenerative feedback and see the variation in the
hysteresis, hysteresis is directly proportional to regenerative
feedback.
