Dynamic signal analyzer is a commonly used electronic instrument used in fields such as sound analysis, mechanical vibration analysis and control system analysis.
Figure 1 is a block diagram of the dynamic signal analyzer. Figure 1. Block diagram of the dynamic signal analyzer
The dynamic signal analyzer consists of the following parts:
1) Anti-aliasing low-pass filter;
2) Analog to digital converter ADC;
3) Digital signal processor: digital frequency conversion, digital filtering, digital signal processing (such as FFT), etc.;
4) Control and display
