以及一锯齿产生器,耦接到该检测器,基于该控制信号调整该锯齿信号的一变迁速率。
A detector detects amplitude of the input signal to generate a control signal, and a saw-tooth generator adjusts a transition rate of the saw-tooth signal based on the control signal.
在相同电压及频率下,方波信号激励下的输出灵敏度最大,其次为正弦波,锯齿波最小。
With the same voltage and frequency, bar signal has the highest sensitivity and next the sine, the least sawtooth.
主要设计思想是使用单片机控制DDS和D/A芯片,得到系统所需的正弦和锯齿波信号。
The main idea of design is using MCU to control DDS and D/A chips, so we can get sine wave and saw tooth signals.
