RC circuitThe RC circuit realizes the following first order transfer function: vout(s)/vin(s) = 1/(RCs+1) The circuit can be used e.g. as an analog first order low pass filter with bandwidth ωb = 1/(RC) [rad/s] or as an example of a process with time-constant dynamics with time-constant T = RC and gain 1. The resistor R can be adjusted with a potensiometer between 2k and 0 Ohm (position 10 and 0, respectively). The capacitor has a fixed value of 220 mF (mikro-Farad). 6th June 2007.
