Demonstrating realtime processing with FIR filters (0009)

FIR filter are realtime filters in that they process data as it comes in. Sample by sample. In contrast the Fourier Transform is not realtime because it requires all samples before it can process the data. Here I show that an FIR filter acts instantly by filtering out 50Hz from my ECG.
