Question 19 of 19
Calculate the necessary gain of the second-stage amplifier to give the whole circuit a voltage gain of 25 decibels, then translate all decibel figures into gain ratios:
Reveal answer- Stage 1 gain = 18 dB = 7.94
- Stage 2 gain = 7 dB = 2.24
- Overall gain = 25 dB = 17.8
Notes:This question is nothing more than “drill” for students to practice decibel/ratio conversions.
