The design and implementation of notch filter for removing power-lin interference from BSPM with 128 channel
To remove low frequency interference effectively from signal by lattice IIR notch filter, the problem of sensitivity to coefficient is investigated.
thin-film notch filter
An adaptive line enhancer based on the above notch filter extracts the fundamental frequency signal from noisy data.
In translation algorithm aspect, slide-window least square lattice combined with adaptive notch filter is used to realize spectral line enhancement, which provides notable improvement in signal-to-noise ratio (SNR) and high convergence speed.
The design principle and the circuit of Theμ p-con- trolled notch filter are emphasized.
Mainly include the design of directional multi microphone system, two channel procession circuit, notch filter, squelch, wide dynamic range compression (WDRC) , tone generator.
The depth of the notch is adjusted by using the adaptive lattice IIR notch filter, so as to improve the SNR of output signal.
subcarrier notch filter
NBI suppression using double notch filtering in DS-UWB receivers
The design of an improved notch filter on surface EEG measurement
Two examples that are IIR notch filter and IIR low-pass filter are given, the stability of filters and the effects of quantification of coefficient are also analyzed.
The notch filter proposed is used to attenuate the adjacent channel interference in the Loran-C receiver.
