Answer / janardhan

The modulation is necessary for signal for its effective
transmission and also it strengthens the information signal.

Why is modification of signal required for transmission Over channel?..

Answer / ashish kashyap

Actually the Message signal which we want to send is of low
frequency and frequency is directly proportional to the
power it contains.

So if it is sent without modulation
it cant travel over long distances.
So we modulate the message signal with a high a frequency
carrier for the effective transmission and also the antenna
size is reduced due to the use of high frequency.

Why is modification of signal required for transmission Over channel?..

Answer / kamal

The low frequency signal will be attenuated it cant able to
travel long distance hence a high frequency is modulated
with it and transmitted

Why is modification of signal required for transmission Over channel?..

Answer / divya

when signal is transmitted for long distances ,the signal will be corrupted of noise so we need the original signal,to get that (we add carrier signal and send it i.e modulation is done) nothing but we amplify the signal
