Given, Transmitted frequency of signal =ω m Carrier frequency <img class="img-fluid question-image" alt="image" src="https://cdn.tardigrade.in/img/question/physics/e5c04482a58489f4542d5d83edf790d0-.png" /> The band width of the filter and amplifier. =(ωm-ωe)+(ωm+ωe) =2 ωm

Q. To transmit a signal of frequency, $ω_{m}$ , with a carrier frequency, $ω_{c}$ , in $A M$ transmission, the bandwidth of the filter and amplifier is

$ω_{m}$

$2 ω_{m}$

$ω_{c}$

$ω_{c} - ω_{m}$

$ω_{c} + ω_{m}$

Given, Transmitted frequency of signal $= ω_{m}$
Carrier frequency

The band width of the filter and amplifier.
$= (ω_{m} - ω_{e}) + (ω_{m} + ω_{e})$
$= 2 ω_{m}$

Q. To transmit a signal of frequency, ωm​, with a carrier frequency, ωc​ , in AM transmission, the bandwidth of the filter and amplifier is

ωm​

2ωm​

ωc​

ωc​−ωm​

ωc​+ωm​

Given, Transmitted frequency of signal =ωm​ Carrier frequency The band width of the filter and amplifier. =(ωm​−ωe​)+(ωm​+ωe​) =2ωm​
