RC Filter

 A resistor-capacitor circuit (RC circuit), or RC filter or RC network, is an lectric circuit composed of resistors and capacitors driven by a voltage or current source. A first-order RC circuit is composed of one resistor and one capacitor and is the simplest type of RC circuits. RC circuits can be used to filter a signal by blocking certain frequencies and passing others. The two most common RC filters are the high-pass filters and low-pass filters.


Learning goals:
  • AC sweep
  • Pspice advanced markers (dB, phase)
  • Bode plot


 What is the cut-off frequency?

 How does the frequency response look like?

 And the phase?



 Use PSpice to see if your calculations are identical to the results from the simulation
