Abstract:
1. A noise-preventing apparatus comprising: an analog-to-digital converting unit that converts received analog source data into digital source data, and outputs the converted data; an input detection signal generation unit which generates an input detection signal containing information on a period from when the analog-to-digital converting unit receives analog source data to when the analog-to-digital converting unit finishes conversion of the received analog source data into digital source data, and transmits the input detection signal; and a noise-preventing clock generation unit which receives the transmitted input detection signal, generates a predetermined clock signal, and based on information on the period included in the received input detection signal, disables the generated clock signal during the period from when analog source data is received to when conversion of the analog source data to digital source data is finished, and releases the disabling and sends the clock signal during a remaining period.
