For a low level AM system, amplifier modulated stage must have                    

A. harmonic devices
B. linear devices
C. non-linear devices
D. class a amplifiers
Answer» B. linear devices
Explanation: in low-level modulation, the generation of amplitude modulated signal takes place at low power levels. the generated am signal is then amplified using a chain of linear amplifiers, which are required to avoid waveform distortion. thus, linear devices are used in low level amplitude modulated system.
