1. 数字信号处理( Digital Signal Processing ,简称 DSP )是一门涉及许多学科而又广泛应用于许多领域的新兴学科。数字信号处理是围绕着数字信号处理的理论、实现和应用等几个方面发展起来的。数字信号处理在理论上的发展推动了数字信号处理应用的发展。反过来,数字信号处理的应用又促进了数字信号处理理论的提高。而数字信...
The objective of this book is to develop signal processing algorithms using Python. Python is an interpreted, object-oriented high-level programming language widely used in various software development fields such as data science, machine learning, web development and more. Digital Signal Laboratory is...
# frequency is the number of times a wave repeats a second frequency = 1000 num_samples = 48000 # The sampling rate of the analog to digital convert sampling_rate = 48000.0 sine_wave = [np.sin(2 * np.pi * frequency * x/sampling_rate) for x in range(num_samples)] 这段代码生成的...
LaTeX source and Python code forThink DSP: Digital Signal Processing in Python, by Allen B. Downey. The premise of this book (and the other books in theThink Xseries) is that if you know how to program, you can use that skill to learn other things. I am writing this book because I...
However, the storage and reproduction of signals (music or else) have changed with the advent of Digital Signal Processing (or DSP). Still, remember CDs? Even if not, the music today is stored as a string of zeros and ones. However, when you play a song, the signal that drives the ...
