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 … WebA Gaussian filter is a good general-purpose filter, and it is the current standardised approach for the separation of the roughness and waviness components from a primary surface (see Section 8.2.3). Both roughness and waviness surfaces can be acquired from a single filtering procedure with minimal phase distortion.

WebSimple Linear-Phase Filter Examples . The example of §10.2.1 was in fact a linear-phase FIR filter design example. The resulting causal finite impulse response was left-shifted (``advanced'' in time) to make it zero 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 …

WebJan 24, 2000 · The deviation from linear phase can be viewed as excursions above and below the flat phase line. An alternative and convenient method is to use delay. The deviations from linear phase will then appear as deviations from constant delay. Remember: phase = -2*pi*f*t. WebPerson as author : Pontier, L.
