Abstract
A method includes accepting an analog input signal including a sequence of pulses of a given pulse shape. The analog input signal is distributed to multiple processing channels (40) operating in parallel. The analog input signal is sampled by performing, in each of the multiple processing channels, the operations of: mixing the analog input signal with a different, respective modulating waveform to produce a mixed signal; filtering the mixed signal; and digitizing the filtered mixed signal to produce a respective digital channel output.
Claims38
A method, comprising:
- accepting an analog input signal comprising a sequence of pulses of a given pulse shape;
- distributing the analog input signal to multiple processing channels operating in parallel;
- and
- sampling the analog input signal by performing, in each of the multiple processing channels, the operations of:
- applying to the analog input signal a respective mixing and filtering operation that filters and mixes the analog input signal with a different, respective modulating waveform to produce a filtered mixed signal;
- and
- digitizing the filtered mixed signal to produce a respective digital channel output.
Apparatus, comprising:
- an input interface, which is configured to accept an analog input signal comprising a sequence of pulses of a given pulse shape;
- and
- a sampling unit comprising multiple processing channels that operate in parallel to one another, each of which processing channels is configured to sample the analog input signal by applying to the analog input signal a respective mixing and filtering operation that filters and mixes the analog input signal with a different, respective modulating waveform to produce a filtered mixed signal, and digitizing the filtered mixed signal to produce a respective digital channel output.
