摘要:
A multi-zone digital-to-analog device is provided with a digital-to-analog (D/A) stage having an input to accept a digital input signal with a data bandwidth of M Hertz (Hz), a clock input to accept a clock signal with a clock frequency of P Hz, and an output to supply an analog value having a bandwidth of M Hz. An upsampling stage has an input to accept the analog value and a clock input to accept the clock signal. The upsampling stage has a device bandwidth of L Hz to supply an analog output signal with a full power bandwidth of K Hz, where (P/2)=M and M
