Parse the frequency of mixed square signals
I'm searching for a way to parse a signal that mixes multiple square waves of different frequencies.
The intended output is the frequency of each of the mixed square waves.
This answer provides an ...

How to get a single point of the rising edge of a square wave in relation to its time?
I am trying to get data from only 1 point of each rising edge and trying to relate it to 1 point of the sin wave at the same time. Ideally, the middle of the rising edge is where I want the sin wave ...

Issues with playing and recording a square wave sound on the same PC
I am learning signal processing. For a hobby project I wanted to transmit and record a simple ASK signal via my soundcard, to see if I can write code to recover the sent data. After playback and ...

the duty cycle in square waves
I've been studying harmonics at school for a while. Speaking of them I discovered that a particular case of harmonic is that of a square wave. I know that this wave is composed of a fundamental and ...

Measuring rise and fall times, of square wave
I have recorded a square wave with scope(bit, controlling some unit).
I want to measure rise/fall time, the time while the bit is on and off using python. I thought of using the 'derrivetive' ...

Fourier coefficients of discrete difference of a square wave
I have a discrete square wave $f(t)$ where $t \in \mathbb{N}$, of amplitude $A$, period $T$ and duty cycle $1/T$
$$
f(t) = \left\{\begin{matrix}
A, & \mathrm{if}\;t=Tn\\
0, & \mathrm{if}\;t\...

DFT and perfect reconstruction of a square wave on a digital computer
I know that in theory, when reconstructing a square wave from its Fourier coefficients, unless we have an infinite amount of them, the resulting reconstruction will have Gibbs ringing artifacts due to ...

How can I generate a time domain square pulse that relies on frequency and not zero centered at MATLAB?
I want to create a square pulse, then use FFT on it. However, this code does not relies on central frequency to generate a pulse, and it is centered at 0 in time and frequency.
...

Confusing regarding triangular wave vs square wave?
I am reading signal processing first by Mcclellan. In chapter 3, I came across the term "discontinous" as shown underlined in attached photo.
Apparently "discontinuous" means having a gap/break but ...

anti-alias filter of square pulses
I'm trying to determine whether or not an anti-alias filter is needed for sampling square waves. The goal is to sample square wave pulses from a video detector with an ADC, do some time-domain digital ...
