The amplifiers X, Y and Z are connected ...

The amplifiers `X, Y` and `Z` are connected in series. If the voltage gains of `X, Y` and `Z` are `10, 20` and `30`, respectively and the input signal is `1mV` peak value, then what is the output signal voltage (peak value)
(i) if dc supply voltage is 10V ?
(ii) if dc supply voltage is 5V?

Text Solution

Verified by Experts

Given input supply `Delta V_(1) =10 ^(-3) V` the output signal voltage
(i) When the DC supply is 10 V then the output is 6.V The output cannot be exceeded by 6V at this voltage.
(ii) When the DC supply voltage is 5V, the output peak will not exceed 5V. so `V_(e) = 5V`
