WITH COMPLETE QUESTIONS AND 100%CORRECT
ANSWERS WITH RATIONALES (VERIFIED AND
GRADED A+)
How is the output frequency determined in a bistable
Multivibrator? - ANSWER-The output frequency is one half
the input trigger frequency.
What is the purpose of a Schmitt trigger? - ANSWER-To
convert any input waveform of any shape and amplitude
into square wave pulses of constant amplitude.
In a Schmitt Trigger when is output high; when is output
low? - ANSWER-The output is high anytime the input
exceeds the threshold.
,2|Page
The output is low anytime the input signal is below the
threshold.
Q1 is a common emitter amplifier that produces a 180
degree phase shift. Each RC network produces a phase
shift as well.
How is frequency determined with the sawtooth oscillator?
- ANSWER-The frequency of the output is determined by
the frequency of the input.

What is the purpose of a blocking oscillator? - ANSWER-
They change DC into short, rectangular pulses that can be
used as timing pulses to trigger other circuits.
Blocking Oscillator - ANSWER-Any oscillator that cuts off
its own oscillations at a predetermined time.
Transconductance (gm) - ANSWER-The amount of control
that the input voltage has over the output current.
Gm= Ioutput/Einput
