Abstract: A hybrid detection algorithm based on F42N150 single-frequency analog notch filter with
Q-factor and elliptic digital bandpass filter is analyzed to solve the detection problem of low-frequency harmonics
in tokamak power supply. The fundamental and 5th-order harmonic, viewed as interference signals, can be
eliminated by boundary optimization of the elliptic digital filter to achieve effective spectrum separation. The
design process is optimized by simulation with MATLAB and the validity of the detection algorithm is verified by
experiments with digital analysis system based on digital signal processing (DSP).

Key words: Harmonic suppression, Single-frequency notch filter, Elliptic digital band pass filter, Boundary
optimization, Low-frequency harmonics
