Electronic Cricket Sound Generator Circuit
The post explains how to build a simple cricket chirping sound generator circuit using a single IC 4093 and a few other passive components. An electronic cricket sound generator is […]
Transistor Multivibrator Circuits Explained
A transistor or BJT multivibrator is a two-stage switching circuit that is configured in a cross-coupled manner. This allows each of the active BJT stages to be regeneratively cross-coupled with the […]
CMOS Astable, Bistable, Monostable Circuits Explained
In this article we discuss how to use the low-cost CD4001 and CD4011 quad 2-input gate CMOS integrated circuits in bistable, astable, and monostable multivibrator applications through forty different manners. […]
IC 4047 Astable, Monostable Circuits
In an IC 4047 astable oscillator circuit, the output of the IC continuously generates a switching ON/OFF signal. Since the output is never in a stable state and constantly switches […]
5 Simple Sine Wave Generator Circuits Explored
A sine wave generator is actually a sine wave oscillator circuit which generates an exponentially rising and falling sinusoidal waveform. The 5 simple sine wave generator circuits presented in the […]
