Relationship between Magnitude and Phase (cf. Oppenheim, 1999)Question: When we only know the magnitude response of an LTI system, can we infer it..
The output of this system is then the magnitude response of the FIR filter. According to linear system theory, the output is the product of the input and the system responses: H(ω)=R(ω)=D(ω) But the magnitude response of a rectangular window has the form shown in Figure 6.19. ...
With hundred-MHz BWs, this typically results in a fairly flat amplitude response across the excitation BW and a linear phase rotation, whose Conclusion This article investigated VNA-based measurement procedures for evaluating the wideband modulation distortion of RF PAs in the presence of load ...
