| Abstract: | In underhole wireless communication technology,low power is one of the most important aspects to consider.In designing the transmitting circuit for under-hole communication,pulse width modulated(PWM) signals are used to drive H bridge power enlargement module,which saves a lot of powers and meets the requirement for low power consumption.This paper mainly describes the application and realization of PWM signals in transmitting circuit.In the end,the test results are briefly explained. |
