    OBJECTIVES To demonstrate the effects that a bypass capacitor has on amplifier voltage gain (Av). To demonstrate the ac operation of the common-emitter (CE) amplifier. INTRODUCTION A common emitter amplifier is one of three basic single-stage bipolar-junction-transistor (BJT) amplifier topologies‚ typically used as a voltage amplifier. In this circuit the base terminal of the transistor serves as the input‚ the collector is the output‚ and the emitter is common to both. The input signal to a
