The Study and Implement of the Digital and Analog Compatible TV Transmitter Power Measurement

摘要

the transmission power of analog TV transmitter is always measured as visual peak power,that is,the power level reaches while the synchronizing pulses are being transmitted,so ordinary power meter can not measure the value of analog TV transmitter power.The paper proposes a new measurement method;a parallel algorithm running in FPGA control high-speed AD,which can measure three analog TV RF signal powers simultaneously,and the paper also provides the signal type recognition and corresponding filter method to achieve digital and analog signals compatible.
