Lecture
This lecture covers the operation of multivibrators, oscillators, and function generators. It explains the principles behind astable multivibrators, waveform generation, and the oscillation period. Additionally, it delves into the functioning of function generators and the principles of nonlinear OPAMP circuits, including voltage comparators, Schmitt triggers, rectifiers, peak detectors, and log and antilog amplifiers. The lecture also discusses timers, such as monostable and astable multivibrators using the 555 IC, and the operation of sample-and-hold amplifiers. Various circuit schematics and operational modes are presented to illustrate the concepts.
