发明名称 DEVICE AND METHOD FOR MULTI-CHANNEL DIGITAL TO ANALOG CONVERSION OF SIGNAL AT DIFFERENT SAMPLE RATE
摘要 PROBLEM TO BE SOLVED: To provide a device capable of processing D/A conversion to a multi-channel having input signal with two or more different sampling speeds. SOLUTION: The device and method for conversing a digital input signal to an analog signal at a different rate sampled comprises digital analog converters (DACA-DACD) to each digital input signal. Each digital-analog converter receives the digital input signal and a clock signal corresponding to the sampling rate of the received input signal. The device can receive a set of sample rate signals denoting the sampling rate to each digital input signal. A control router uses the corresponding clock signal and the sample rate signal for distributing each digital input signal to the corresponding digital-analog converters. A clock error signal routes the digital input signal to the DAC in the same way as the operation of the DAC. COPYRIGHT: (C)2007,JPO&INPIT
