There are 3 types of multivibrators: astable, monostable, and bistable. This astable multivibrator is an oscillator that generates rectangular pulses. It uses transistor switches and RC networks. The ...
The figure shows a 555 timer used as an astable multivibrator. Determine the values t1, t2, frequency and duty cycle of the output waveform. When a 555 timer operates as an astable multivibrator, the ...
