Question

How are amplitude modulation and frequency modulation techniques similar?

Both are used by cell phones to produce images.
Both transform electrical signals into sound waves.
Both modify the pulse of a carrier wave.
Both are used by radio stations to transmit sound.

Answer 1

Answer:

D. Both are used by radio stations to transmit sound

Explanation:

The main difference between both modulations is that in frequency modulation, the frequency of the carrier wave is modified as per the transmit data, while in amplitude modulation, the carrier wave is modified according to the data. because of this it can NOT be A, B, or C but it CAN be D

Answer 2

The amplitude modulation and frequency modulation techniques similar as , Both are used by radio stations to transmit sound.

So, option D is correct one.

What is difference between amplitude modulation and frequency modulation techniques ?

• The primary distinction between the two types of modulation is that , amplitude modulation modifies the carrier wave in accordance to data, frequency modulation modifies the carrier wave's frequency according to the transmit.

• The frequency modulation operates between 88 and 108 MHz and the amplitude modulation operates between 535 and 1705 KHz.
