Multivibrators

Multivibrators are a type of integrated circuit (IC) that is used to generate periodic square wave or pulse signals. They are made up of two or more amplifying stages that are interconnected in a particular way, and that can oscillate between two stable states. Multivibrators are commonly used in a variety of applications, such as oscillators, pulse generators, and time-delay circuits. They may also be used in conjunction with other logic gates and circuits to implement more complex logical operations. Multivibrators are typically classified by the type of logic they use, such as TTL (transistor-transistor logic) or CMOS (complementary metal-oxide-semiconductor), and by the frequency and duty cycle of the signals they generate.
