- Frequency Distortion occurs in a transistor amplifier when the level of amplification varies with frequency
- Non-uniformity in the rate of change between the base voltage and the collector current means that for a given DC bias at the base, a sinusoidal signal would have its negative peaks rounded off and the positive peaks sharpened up which causes harmonic distortion
- Frequency distortion due to harmonics occurs because of reactive elements such as capacitance or inductance
