What is the "waterbed effect" in control system design?
This effect, sometimes called the waterbed effect, can be explained mathematically in terms of integral inequalities imposed on the closed loop transfer functions. In the basis of such results is the affine …

Aug 24, 2025 · What is the "waterbed effect" in control system design? I recently stumbled across some notes on the "Waterbed effect" in some notes by A. Megretski for an MIT course on "multivariate …
What is the Wrap-Around Phenomenon in FFT?
Aug 24, 2024 · 1 If I take FFT of a finite sequence and take longer length of IFFT of the frequency domain data by padding zeros with it, how will the wrap around of DFT effect the procedure? It would …
Antenna impedance mismatch effect on receiver IC
May 20, 2025 · It is directly related to signal/noise ratio, or perhaps distortion of your signal. Many things can effect SNR; the receive antenna impedance is one of many. Note that "RSSI" stands for …
Border effects / artifacts for spectral filtering of images
Apr 24, 2024 · This works pretty well in my case, however, I don't understand the border artifacts that appear in the filtered image (see below). The problem occurs for different filters (step, linear, …
Effect of changing sampling rate of an audio signal
Jun 22, 2023 · What will happen when sampling rate of an audio signal is changed? Does it changes signals duration or signals total sample or both?
fft - What can be done, on top of windowing, that can reduce ...
Dec 15, 2023 · This has significantly reduced the number of clicks in my audio, but when I significantly degrade the audio, I can still hear some clicking, which I have noticed is not present in other plugins …
Sampling frequency offset vs carrier frequency offset effects
Jun 17, 2022 · Your proposed technique only works for a very small set of signals. Sinusoidal signals fall into that category. If you're signal has a nonzero bandwidth you will need to resample it properly to …
Boundary effects with scipy.fftconvolve after convolution
Apr 22, 2021 · The problem is that such boundary effect affects another part of the calculation that depends on the obtained signal. I would like to know a way to circunvent this, while still having …
