Embodiments of the present invention provide a method and apparatus for compressed sensing. In some embodiments, the apparatus ( 10 ) generally includes a receiving element ( 12 ) operable to receive an input signal, an integrate/dump circuit ( 14 ), a sampling element ( 16 ), and a processor ( 18 ). The integrate/dump circuit ( 14 ) is operable to integrate at least a portion of the received signal to provide an integrated signal and the sampling element ( 16 ) is operable to sample the integrated signal at a first sampling rate which is less than the Nyquist rate for the input signal. The processor ( 18 ) is operable to form a compressed sensing matrix utilizing a first set of time indices corresponding to the first sampling rate, form a measurement vector utilizing at least a portion of the sampled signal, and reconstruct at least a portion of the input signal utilizing the compressed sensing matrix and the measurement vector.
