1. Electronic Communication System:
Purpose:
Transfer information from one place to another.
Information is transmitted, processed and received using electronic circuits.
Power Gain & Voltage Gain: In terms of ratio:
For power, Ap = Poutput/Pinput [unitless]
For voltage, Av = Voutput/Vinput [unitless]
In terms of Decibels:
For power, Ap = 10 log10 (Poutput/Pinput) [dB]
For voltage, Av = 20 log10 (Voutput/Vinput) [dB]
