Frequency response of an amplifier
Fig. 9-1 shows the typical frequency response of an amplifier. At low frequencies the output voltage decreases because of coupling and bypass capacitors. At high frequencies, the output voltage decreases because of transistor and stray wiring capacitance.
Where the output voltage is 0.707 of Vmax.
Is the band of frequencies between 10 * f1 and 0.1 * f2.
Ex: Find the midband of an amplifier with f1 = 5 Hz and f2 = 100 KHz.
Midband: 50 Hz - 10 KHz
