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.
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.
同时变频变幅的TFFP锯齿波扫描信号可以灵活地改变系统的扫描范围,进一步提高了系统的解调速度。
While the alterable frequency and scope sawtooth sweep signal for TFFP can neatly change the scanning range of the system, which is more improved the demodulation speed.
