EVENT-DRIVEN SPATIO-TEMPORAL SHORT-TIME FOURIER TRANSFORM PROCESSING FOR ASYNCHRONOUS PULSE-MODULATED SAMPLED SIGNALS

摘要

A method of processing asynchronous event-driven input samples of a continuous time signal includes calculating a short-time Fourier transform (STFT) output based on the event-driven input samples. The STFT output may be calculated by expressing an encoding pulse and an STFT window function as a sum of complex weighted causal complex exponentials. The method further includes interpolating output between events.
