A diode detector is used to detect an amplitude modulated wave of 60% modulation by using a condenser of capacity 250 pico farad in parallel with a load resistance 100 kilo ohm. Find the maximum modulated frequency which could be detected by it.

A

10.62 MHz

B

10.62 kHz

C

5.31 MHz

D

5.31 kHz

Text Solution

Verified by Experts

The correct Answer is:
B
For how pass filter, frequency greater than `(1)/(C)` can't pass through filter
`implies flt(1)/(C)`
`implies flt(1)/(RC)=4xx10^(4)Hz`
`=40KHz`
in given option maximum frequency below `40KHz` is `10.62KHz`

Assertion: AM detection is the process of recovering the modulating signal from amplitude modulated waveform wich is carried out using a rectifier and an evelope detector. Reason: Amplitude modulated waves can be produced by application of the message signal and the carrier wave to a non-linear device followed by band pass filter.

Both amplitude modulation (AM) and frequency modulation (FM) are used for radio broadcasting. The amplitude of the high frequency carrier wave is varied or modulated in accordance with the variations in the amplitude of the audio signals that are to be transmitted, in te process of amplitude modulation in frequency modulation te amplitude of the carrier remains constant but its frequency is varied inn accordance withh the audio signal. Reception with AM signals is in general is affected by interference of various kinds ad elaborated equipment is required for FM broadcast. In india the radio signals are boarcast using-
