Notch filters are invariably used in communication, control, instrumentation, and bio-medical engineering, besides a host of other fields, to eliminate noise and power line interferences. Digital ...

Abstract: An efficient digital notch filter for 50Hz noise eliminated from low frequency photoacoustic gas sensing signal is presented in this paper by a Matlab program. The digital notch filter is ...

Abstract: In view of the mechanical resonance existing in electric servo mechanisms, which affects the system bandwidth and steady-state accuracy, a dual-T notch filter with adjustable depth and width ...
