Give your answer in the following table:
Question No. 3
Suppose power P of a signal is increased 30 times after passing through an amplifier. By writing all necessary formulas and calculation steps, you are required to calculate amplification (power gain) in proper unit.
Solution: Av=Input voltage/output voltage AI=input current/out put current
Ap=av*ai
Amplifiers gain given in decibels (dB)
Av=20logAv Ai=20log Ai Ap=10log Ap
Note calculate the values by your selfe
