ad9850在发射机激励器中的应用

激励器是中波发射机的重要组成部分,其稳定性对同步广播尤为重要,采用直接数字频率合成器ad9850,简化了原来的发射机电路,减少了故障率,实际测试输出为理想正弦波。频率稳定度仅仅取决于高稳定晶体振荡器,与外围电路无关。方便调试和使用。

Actuator is an important component of the medium wave transmitter,the stability of the synchronous broadcasting is particularly important,using direct digital frequency synthesizer ad9850,simplifies the original transmitter circuit,reduce the failure rate,the actual test output sine wave for a noble ideal.Frequency stability depends on high stability crystal oscilator,only has nothing to do with the peripheral circuit.Convenient debugging and use.
