Time Domain and Frequency Domain Analysis of ADC

Here, we introduce the concepts of time domain and frequency domain. The time domain shows how the amplitude of a signal varies over time. In the time domain example, we create an unusual waveform by adding two sine waves. One is a sine wave with a peak voltage of 1V and a frequency of 1kHz, … Read more

FFTW: The Powerful C Library for Fast Fourier Transform

Hello everyone! Today I want to share with you a powerful C library – FFTW (Fastest Fourier Transform in the West). It is one of the fastest open-source libraries for Fourier Transform and is widely used in fields such as signal processing and image processing. Don’t worry if you don’t know what Fourier Transform is; … Read more
