Gain Factor Solution

STEP 0: Pre-Calculation Summary

Formula Used

Gain Factor = Amplifier Gain in Mid Band/Mid Band Gain
K = A_m/A_mid
This formula uses 3 Variables

Variables Used

Gain Factor - The gain factor can be positive or negative and has a magnitude usually larger than unity. K=V2/V1, which is the internal voltage gain of the network.
Amplifier Gain in Mid Band - (Measured in Decibel) - Amplifier Gain in Mid Band is a measure of the ability of a two-port circuit to increase the power or amplitude of a signal from the input to the output port.
Mid Band Gain - The Mid band Gain of a transistor is the transistor's gain at its mid frequencies; the mid band gain is where the transistor's gain is at the highest and most constant level in its bandwidth.

STEP 1: Convert Input(s) to Base Unit

Amplifier Gain in Mid Band: 12.2 Decibel --> 12.2 Decibel No Conversion Required
Mid Band Gain: 32 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

K = A_m/A_mid --> 12.2/32

Evaluating ... ...

K = 0.38125

STEP 3: Convert Result to Output's Unit

0.38125 --> No Conversion Required

FINAL ANSWER

0.38125 <-- Gain Factor

What is 3 dB bandwidth of a filter?

The 3 dB bandwidth of an electronic filter or communication channel is the part of the system's frequency response that lies within 3 dB of the response at its peak, which, in the passband filter case, is typically at or near its center frequency, and in the low-pass filter is at or near its cutoff frequency.
