Abstract
설외기의 호출스위치를 누르면 호출신호 발생부가 동작하고, 그에 따라 7KHz발진부에서 7KHz 정현파신호가 출력되어 변조부에서 5.5MHz반송파를 주파수 변조시켜 실내기로 송신하고, 실내기에서는 그 신호를 7KHz필터를 통해 7KHz 신호만 통과시키고 정류부에 의해 정류하여 차임벨 발생부를 동작시켜 차임벨 소리를 발생시켜 호출하게 된다.When pressing the call switch of the outside unit, the call signal generator operates, and accordingly, a 7KHz sine wave signal is output from the 7KHz oscillator, and the modulator transmits the frequency by modulating the 5.5MHz carrier to the indoor unit. Only the signal is passed and rectified by the rectifier to operate the chime generator generates a chime sound to call.
