| Abstract: | This paper introduces the design and implementation of PPM modulator.According to the peculiarity of the PPM modulation,we use the method of data latch and counting.We specify the modulator parameters by useing of the software,improving the application flexibility of the system. To enhance the reliability of the modulator,we utilize hardware interrupt to make the system communicate withcom puter. We also use EPLD programmable logic device to implement the counter,flip latch, and control logic circuit,largely simplifying the circuit implementation.The simulating result is presented too. |
