Abstract:
1. A digital signal-rate converting system comprising: first means for receiving a digital input signal characterized by a first rate; and second means for interleaving said digital input signal in accordance with a predetermined pattern and providing an adjusted-rate digital signal in response thereto, said adjusted-rate digital signal representative of said digital input signal; wherein said digital signal-rate converting system is an input interface of a rate-converting Digital-to-Analog converter (DAC), wherein said rate-converting DAC includes a 1-bit DAC module for receiving said adjusted-rate digital signal and providing an analog output signal with a desired bandwidth or center frequency in response thereto, and wherein said adjusted-rate digital signal is an approximation of said digital input signal and is characterized by a rate based on a desired center frequency of said analog output signal.
