Calculating Output Voltage of an Amplifier with RC Coupling Network

Click For Summary
SUMMARY

The discussion focuses on calculating the output voltage (Vo) of an amplifier with an RC coupling network consisting of a resistor (R = 1 kΩ) and a capacitor (C = 5 mF). The input signal is a sinusoidal voltage source with an r.m.s. amplitude of 200 mV. The output voltage is to be calculated at frequencies of 10 Hz, 100 Hz, and 1 kHz, considering the input impedance of the amplifier is significantly larger than the resistor value. The key to solving this problem lies in determining the impedances of both the resistor and the capacitor at the specified frequencies.

PREREQUISITES
  • Understanding of RC coupling networks
  • Knowledge of impedance calculations for resistors and capacitors
  • Familiarity with sinusoidal voltage sources
  • Basic principles of amplifier circuits
NEXT STEPS
  • Calculate the impedance of the capacitor at 10 Hz, 100 Hz, and 1 kHz
  • Determine the output voltage using the voltage divider rule
  • Explore the effects of varying resistor and capacitor values on output voltage
  • Study the frequency response of RC coupled amplifiers
USEFUL FOR

Electronics students, audio engineers, and circuit designers who are working with amplifier circuits and need to understand the impact of RC coupling on output voltage.

Hi I am struggling to answer this question:

The input coupling circuit of the amplifier shown in the figure consist of an RC network, with R = 1 kW and C = 5mF fed by a sinusoidal voltage source of r.m.s. amplitude of 200 mV. Assuming that the input impedance of the amplifier is, at all frequencies, so much larger than 1 kW that it can be neglected, calculate the output voltage Vo at 10Hz, 100Hz and 1kHz.

I would really appreciate any help, or if someone could point me in the right direction.

Thanks in advance

Don't know if you're still working on this, I just saw it.

What are the impedances of the resistor and of the capacitor?
