The Design of Interference Generator for Grid Based on 89S52

Abstract:

The minimum microcontroller system is adopted in this paper to produce sine wave, achieve key control, and realize frequency display and measurement, which enable the circuit to automatically change and measure the filter output frequency. In the system 4011 chip and external RC circuit adjust pulse width and the number of bursts, Two-stage second-order active band-pass filter is used to filter out interfering signals so to get the fundamental signals. The 89s52 microcontroller programming regulate the signal frequency and amplitude which is realized through keyboards and shown on LED
