HK0402 - Active Network Synthesis

ECG signal processing with MATLAB and filtering with LTspice

MFB topology is used for active filtering. Here, there are two functions, one is for high-pass MFB filter and the other one is for low-pass MFB filter. These functions take filter parameters (Q_factor, cut-off frequency, gain and available capacitor and resistor values) as input. It estimates all the possible R/C combinations that satisfies given filter parameters and returns them as a table.
