1. conversion device: electronic components such as transformers or operational amplifiers are used for conversion, and square waves with different amplitudes are converted into square waves with the same amplitude by amplifying or reducing the signal amplitude.
2. Noise filter: Use noise filters such as low-pass filters to filter out the high-frequency part of the square wave, so as to keep its amplitude within a suitable range, thus obtaining a square wave with the same amplitude.
3. Modulation and demodulation: The square waves with different amplitudes are converted into square waves with the same amplitude by modulation and demodulation technology. The specific method is to use square waves with different amplitudes as carriers, add a modulation signal with the same frequency, and then demodulate the original square wave signal to get square waves with the same amplitude.
4. Digital signal processing: In the digital system, square waves with different amplitudes can be converted into square waves with the same amplitude by using digital signal processing technologies such as normalization and denoising. For example, for a square wave with a large maximum amplitude, its value can be divided by the maximum amplitude, so that a square wave with the same amplitude can be obtained. In addition, the denoising algorithm can be used to filter out unnecessary interference components in the square wave and keep its amplitude stable.
