A voltage amplifier receives 15 mV as input and produces 5 V as output. Calculate both the linear and decibel gains.
💡 Hint: Use the voltage gain formula followed by the dB conversion formula.
Determine the bandwidth of an amplifier if the lower cutoff frequency is 100 Hz and the upper cutoff frequency is 20 kHz.
💡 Hint: Consider how to calculate the range by subtracting the lower from the upper frequency.
