ABSTRACT:
A system for emulating characteristics of a plurality of analog-to-digital converter (ADC) architectures in the conversion of an analog signal to a digital signal. The system comprises a flash ADC for sampling the analog signal and outputting a digital representation of a sample of the analog signal, a digital-to-analog converter (DAC) for supplying the reference values to the flash ADC, and a digital signal processor (DSP) for processing the digital representation of the sample and outputting the digital signal. The digital representation is based on a comparison of the sample to reference values and comprising a number of bits of resolution. The DSP is configured to send a modifiable control signal defining the reference values to the DAC.
