Download Solution PDFDirections: It consists of two statements, one labeled as the ‘Statement (I)’ and the other as ‘Statement (II)’. Examine these two statements carefully and select the answer using the codes given below:
Statement (I): An astable multivibrator is also called a free-running oscillator.
Statement (II): An astable multivibrator circuit forces an operational amplifier to operate in the saturation region.Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFAstable Multivibrators are free running oscillators which oscillate between two states continuously producing two square wave output waveforms. These both states are not stable as it changes from one state to the other all the time.
The Op-amp Multivibrator is a non-inverting op-amp circuit that produces its own input signal with the aid of an RC feedback network. It forces an operational amplifier to operate in the saturation region.Last updated on May 28, 2025
