- In common emitter connection, when the input signal voltage increases in the positive sense, the output voltage increases in the negative direction and vice-versa. In other words, there is a phase difference of 180° between the input and output voltage in CE connection. This is called phase reversal.
- The phase difference of 180° between the signal voltage and output voltage in a common emitter
amplifier is known as phase reversal.
