Gain at Mid and High Frequencies Solution

STEP 0: Pre-Calculation Summary

Formula Used

Gain Factor = Mid Band Gain/(1+(Complex Frequency Variable/Upper 3-dB Frequency))
µ = A_m/(1+(s/ω_hf))
This formula uses 4 Variables

Variables Used

Gain Factor - Gain factor of an amplifier is the factor by which the input power is amplified.
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.
Complex Frequency Variable - (Measured in Hertz) - Complex frequency variable describes a sinusoidal signal with increasing (positive σ) or decreasing (negative σ) sine wave.
Upper 3-dB Frequency - (Measured in Hertz) - Upper 3-dB frequency is the cutoff frequency of an electronic amplifier stage at which the output power has dropped to half of its mid-band level.

STEP 1: Convert Input(s) to Base Unit

Mid Band Gain: 20.9 --> No Conversion Required
Complex Frequency Variable: 2 Hertz --> 2 Hertz No Conversion Required
Upper 3-dB Frequency: 30.417 Hertz --> 30.417 Hertz No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

µ = A_m/(1+(s/ω_hf)) --> 20.9/(1+(2/30.417))

Evaluating ... ...
