Digital Signal Processing (DSP) is applied to the collected time-domain signals to obtain their frequency-domain results. When a signal is transformed from the time domain to the frequency domain, there are specific DSP terminologies, and these terms have important mathematical relationships with each other. Are you clear about them? The following are the DSP terminologies. … Read more

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
In industrial sites, the noise generated by equipment operation not only affects the working environment but may also obscure important equipment failure signals. As an engineer with over ten years of experience in industrial noise control, I will detail how to utilize Python for efficient noise monitoring and signal separation. 1. Overview of Signal Processing … Read more

We know that the Fast Fourier Transform (FFT) is an important mathematical tool in signal processing. Generally speaking, the result of the Discrete Fourier Transform (DFT) of a signal with N points will also have N data points in the frequency domain. However, in practical applications, performing FFT on a signal often involves the issue … Read more
