Here, the samples are irregularly spaced threshold-based samples. In this paper, we investigate the problem of sampling finite-rate-of-innovation (FRI) signals using an IF-TEM.  ...  Classical sampling is based on acquiring signal amplitudes at specific points in time, with the minimal sampling rate dictated by the degrees of freedom in the signal.  ...  In the sub-Nyquist regime, finite-rate-of-innovation (FRI) signals are widely studied [1] , [22] , [23] .  ...
