1. An apparatus for reconstructing an input signal, the apparatus comprising:

  • a receiving element operable to receive the input signal;

    an integrate/dump circuit coupled with the receiving element, the integrate/dump circuit operable to integrate at least a portion of the received signal to provide an integrated signal and dump the integrated portion of the received signal,a sampling element coupled with the integrate/dump circuit, the sampling element operable to receive the integrated signal and sample the integrated signal at a first sampling rate to provide a sampled signal, the first sampling rate being less than the Nyquist rate for the input signal; and

    a processor coupled with the sampling element, the processor operable toform a compressed sensing matrix utilizing a first set of time indices corresponding to the first sampling rate,receive at least a portion of the sampled signal,form a measurement vector utilizing at least a portion of the sampled signal, andreconstruct at least a portion of the input signal utilizing the compressed sensing matrix and the measurement vector.
