I'm writing a synthesizer using numpy and python. I've run into a problem where concatenating sine waves causes 'pops' or 'clicks' when they are outputted to audio, say, via ...

The problem (taken from here) asks for possible sampling rates that will not cause aliasing in the following frequency spectrum:
The range of possible values after some math is given as $B_2 < f_s ...

I was trying to understand more about image compression using the Wavelet transform and I got quite confused about the down-sampling step. I took a picture from here for reference:
At each step a ...

This is probably a very stupid question. In many places (e.g. here), the Butterworth filters, e.g. lowpass, are described as being "allpole" filters, that have all of these poles on the unit ...

I am trying to implement a notch filter by placing zeros and poles. I found in this thread how to specify the frequency to be filtered out (referred to as $\omega_n$ in previous link,) but it is not ...

I first thought it would be 3 dimensions (one for R, one for G, one for B). However what about the width and height?
More a physics/image processing question I think.
So, I have a few possible answers ...

I am trying to implement sampling and reconstruction using simulink and as far amplitude(magnitude) values are concerned ,i have exactly same values but there appears phase shift when i try to see ...

Greatest hits from previous weeks:

|
Welch's method has been my go-to algorithm for computing power spectral density (PSD) of evenly-sampled timeseries. I noticed that there are many other methods for computing PSD. For example, in ...

Can anyone state the difference between frequency response and impulse response in simple English?

|
Not sure if this is the right place to ask, feel free to move it if any other site suits this better.
Anyway I am referring to QAM modulation used in US Cable TV. I know it comes under Annex B which ...

I was just learning about the frequency domain in images.
I can understand the frequency spectrum in case of waves. It denotes what frequencies are present in a wave. If we draw the frequency ...

I am trying to sample a sine wave and plot it's frequency components, but I am having problems implementing it.The result of taking 65536 samples of one cycle of a sine wave with max amplitude 1 and a ...

I have been working on the topic of camera pose estimation for augmented reality and visual tracking applications for a while and I think that although there is a lot of detailed information on the ...

I have a transfer function $$H(z)=\frac{1+1.2z^{-1}+0.8z^{z^-2}}{1-0.9z^{-1}}$$ from which I'm supposed to sketch the magnitude and phase response. I know that you can transform $z=e^{j\omega}$ to get ...

Can you answer these questions?

I'm a beginner.
If I am using a Convolutional Neural Networks with Triplet Loss as a loss function (also combined with GAN and a Classifier) for building a model that performs Speaker Verification, ...

I am a complete beginner and i had some problems figuring out what i had to do to solve this. I apologize in advance for not putting the proper tags but i didnt know what to put in there or if even if ...
