Question

Difference between direct and indirect method of fm generation

Answer 1

Answer:

Direct FM For direct FM, the instantaneous frequency is directly varied with the information signal. The carrier frequency is varied using an oscillator where its resonant frequency is determined by variable components. ... Indirect FM As mentioned in the lecture notes, FM and PM are related to one another.

Answer 2

Diffreence between direct and indirect FM is given below.

Explanation:

• There are two types of methods for FM generation.
• Direct FM
• Indirect FM
• In direct FM, as the information signal s received the instantaneous frequency is directly varied with the information signal.
• While an oscillator is used to change the carrier frequency where its resonant frequency is determined by variable components.
• In Indirect FM the signal is not received directly and the frequency does not vary with the signal. it is a combination of  FM and PM are related to one another.
