    How ths multivibrator works? I cant understand.Because its pulse not given to base of transistor.

    Re: multivibrators

    The transistor is in the common base configuration. In this configuration, the input is at the emmiter.

    so what happend to the transistor when a pulse is comming.if it turn on ?(revers bias or forword bias)

    When a negative pulse arrives at the emitter, its voltage is lower than the base voltage, so the transistor is forward biased.
