    RC coupled amplifier at high frequency, Lecture XXIV and XXV.

    In our last lecture we discussed the case of a single stage RC coupled amplifier, a common emitter transistor circuit. for its response at low frequencies, i.e. frequencies that are less than 50 Hz. Today we will discuss what changes are going to be effected in the same circuit when we pass signal at high…

  • RC coupled amplifier and its low frequency response, Lecture-XXIII.

    RC coupled amplifier and its low frequency response, Lecture-XXIII.

    In our last two lectures we discussed in much detail the case of the single stage common emitter RC coupled amplifier. There we discussed the elements of the circuits (such as why a given capacitor is required and so on), determined the currents in various components (such as base and collector) and eventually calculated the…
