Q.

For which of the modulated system, the linear amplified modulated stage is used?

A. low level amplitude modulated system
B. high level amplitude modulated system
C. high level frequency modulated system
D. low level frequency modulated system
Answer» A. low level amplitude modulated system
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 amplified modulated stage is used in low level amplitude modulated system.
