ABSTRACT:
A method and apparatus for a multi-mode and multi-rate telemetry transmitter includes a digital baseband lineup, a digital-to-analog converter (“DAC”), and an analog reconstruction filter. The digital baseband lineup may be programmed to any desired bit rate, enabling the transmitter to support multi-rate capabilities. Different coefficients and numerical values may be programmed in the digital baseband lineup to support any desired modulation scheme, enabling the transmitter to support multi-mode capabilities. The digital baseband lineup may be designed by implementing up-sampling stages, down-sampling stages, and digital filters in a variety of arrangements.
