电子技术综合设计实验报告

采用555定时器，由555产生方波信号，方波经RC积分电路积分后即可得到三角波，再由三角波通过RC积分电路得到正弦波，该方案集成度高，同时产生正弦波的方法简单、易调。但实际遇到种种困难不能在短时间内解决，所以又设计了用运放电路产生正弦波的电路，并验证了其正确性。-General design of electronic technology experiment using 555 timer report, produced by the 555 square-wave signal, square wave by the RC integral circuit points can be obtained after the triangular wave, and then by the triangle wave through the RC integral circuit to be sinusoidal, the program integrated high, at the same time generate sine-wave method is simple and easy to tune. However, the actual difficulties should not resolved within a short time so designed operational amplifier circuits with sine wave generated circuit and verify its correctness.
