1. Signal frequency: The frequency of the square wave determines the periodic waveform change. The higher the frequency, the faster the waveform changes.
2. Signal amplitude: The amplitude of the square wave determines the variation range of the voltage up and down the waveform. The larger the amplitude, the larger the amplitude of the waveform change.
3. System response: When the square wave signal passes through a certain system, the frequency response characteristics of the system will cause changes in the waveform. For example, the system may have attenuation or delay effects on low-frequency signals, resulting in compression or delay of the waveform.
4. Signal distortion: The signal may be affected by noise, distortion and other factors during transmission, resulting in a change in the shape of the waveform.
The combined influence of these factors leads to the change of square wave response waveform.
The frequency is large, that is, the cycle is small, the capacitor charge and discharge time is small, so the capacitor voltage waveform is reduced on the basis of the original (in appearance), and the value is smaller
