Questions tagged [signal-processing]

Known as digital signal processing, or DSP for short, a signal is essentially a dynamic property of something that carries information. However, in the realm of digital technology, 'signal' typically refers to data streams or blocks that are either received or transmitted, often representing real-world measurements like sound levels, brightness, or pressure over a period of time or distance. The term 'processing' involves manipulating, examining, or categorizing this data in order to extract or alter the underlying information conveyed by the signal being analyzed.

creating a parabolic shape within a section of a cyclical wave using the numpy library

A repetitive signal with slight variations in each cycle occurs approximately every second. Each cycle differs slightly in duration and content within certain parameters. The signal data consists of a thousand x,y coordinates per second, with a small but s ...

Python implementation of a bandpass filter

I need to implement a bandpass filter in Python using a 128-point Hamming window with cutoff frequencies of 0.7-4Hz. The challenge is that the samples for my signal come from images (1 sample = 1 image) and the frames per second (fps) can vary. Is there a ...

Developing a deconvolution algorithm with the Python programming language

Admitting my lack of expertise in DSP in python, I am determined to deconvolute two sound signals using this programming language. My goal is to extract the room impulse response by analyzing a sinesweep input signal and its corresponding output record. ...
