Second-Order Polynomial, Interpolation-Based, Sampling Rate Converter and Method and Transmitters Employing the Same |
摘要 |
A sampling rate converter, a method of performing digital sampling rate conversion and a wireless transmitter incorporating the filter or the method. In one embodiment, the sampling rate converter includes: (1) an input configured to receive digital data from a first clock domain sampled at a first sampling rate, (2) an output configured to provide digital data to a second clock domain sampled at a second sampling rate that differs from the first sampling rate and (3) a filter with a second-order, polynomial-based impulse response coupled to the input and the output and configured to apply coefficients having only one nonunitary divisor to the digital data from the first clock domain.
