(i) what is meant by regeneration
A
noise/distortion is removed (from the signal)
the (original) signal is reformed.
or
signal detected above/below a threshold creates new signal
of 1s and 0s (B1)
2
Q
Explain why an analogue signal cannot be regenerated.
A
The noise is superposed on the sound signal.
the noise will also get amplified during the regeneration.
3
Q
What is the formula for decibel ratio?
A
10log(Pout/Pin)
