【Guangxi Normal University Competition】Arbitrary Waveform Generator

1. Task: Design and manufacture an arbitrary waveform generator that can generate sine waves, square waves, and triangle waves. The waveform generator can ensure constant voltage output within a certain range.

2. Requirements
1. Basic requirements
(1) The waveform generator can generate three periodic signals: sine waves, square waves, and triangle waves;
(2) The frequency range of the output waveform is 100Hz~100kHz; the frequency is adjustable, and the frequency step interval is ≤
100Hz;
(3) Under 50Ω load conditions, the maximum peak-to-peak value
of the output voltage is ≥2V; (4) The function of displaying the type, repetition frequency (period) and amplitude of the output waveform;
(5) There is no obvious distortion when observed with an oscilloscope.
2. Development part
(1) The frequency range of the sine signal is extended to 1Hz~10MHz, and the
output .
(2) With output frequency and frequency step setting function;
(3) Under 50Ω load condition, the maximum output voltage peak-to-peak value is ≥5V;
(4) With waveform type, frequency and amplitude display function;
(5) Can output at least one arbitrary waveform.
