| Abstract: | Based on LPC2138, this programmable filter is made up of programmable amplifier, analog filter, keyboard and LED etc. The parameters are modified by keyboard in order to control amplification and cutoff frequency by step. Experiment data indicated this method is correct and feasible. |
