Question

what is a.c voltage gain and d.c voltage.gain
​

Answer 1

Hey Mate!!

DC voltage gain (also called steady-state voltage gain) is the ratio: output voltage and input voltage for a direct voltage input.

• DC gain is simply the gain at steady state, which can be thought of as the frequency ZERO hz. ... The ratio of the DC current or voltage “output” to the DC “input” current or voltage is the DC gain and expressed as a single number. A DC gain of 2 would mean the output (current or voltage) would be 2 times the input.

AC voltage gain is the same formula, but for unbiased sinusoidal input and output voltages.

• The ratio of the AC component of the output to the AC component of the input is called the "gain". The gain is usually between 5 an 20.

Hope this helps you!!
