Measuring group delay through a linear phase filter

In signal processing, linear phase is a property of a filter where the phase response of the filter is a linear function of frequency. The result is that all frequency components of the input signal are shifted in time (usually delayed) by the same constant amount (the slope of the linear function), which is referred to as the group … See more A filter is called a linear phase filter if the phase component of the frequency response is a linear function of frequency. For a continuous-time application, the frequency response of the filter is the Fourier transform of … See more When a sinusoid$${\displaystyle ,\ \sin(\omega t+\theta ),}$$ passes through a filter with constant (frequency-independent) group … See more • Minimum phase See more Systems with generalized linear phase have an additional frequency-independent constant $${\displaystyle \beta }$$ added to the phase.

WebDescription. z = pmdemod(y,Fc,Fs,phasedev) demodulates the phase-modulated signal y at the carrier frequency Fc (hertz). z and the carrier signal have sampling rate Fs (hertz), where Fs must be at least 2*Fc.The phasedev argument is the phase deviation of the modulated signal, in radians.. z = pmdemod(y,Fc,Fs,phasedev,ini_phase) specifies the … WebSpectral Phase. As for the phase of the spectrum, what do we expect?We have chosen the sinusoid phase offset to be zero. The window is causal and symmetric about its middle. Therefore, we expect a linear phase term with slope samples (as discussed in connection with the shift theorem in §7.4.4).Also, the window transform has sidelobes which cause a … Webthe conversion of the phase fluctuations into the noise sideband of the carrier.
