RC Band Pass Filter

The band pass filter passes frequency components within a certain range, and rejects all the frequency component which is outside this band. The following curve shows the respond of an ideal band pass filter. Lets say we have a low pass filter with cut-off frequency fc1, and a high pass filter with cut-off frequency fc2, […]

RC High Pass Filter

A high pass filter passes all the frequency component that has frequency above the cut off frequency and rejects all frequencies from 0 Hz to the cut off frequency. The following curve shows the respond of an ideal high pass filter. The passive RC high pass filter circuit can be designed in two combinations like resistor and capacitor (passive RC HPF); […]

PID Circuit Implementation

I decided to set up a circuit with a peicewise linear input which is an input that is defined to have 0 volts from time t = 0 to time t = 1ms, and have for example an input of 2 volts for time t > 1ms. There is a sudden change of input voltage […]
