The Origins of Digital Signal Processing

Date:  6 June 2023

Time:  5:00-6:30 PM

Location: T.B.A


It was in the mid-sixties that what is today known as Digital Signal Processing (DSP) emerged from the analog realm. Many advances, which today are taken for granted, were created by visionary pioneers who sensed the transformative power of the advancing digital world for representing and processing signals. Commemorating the 75thanniversary of the IEEE SP Society, the ICASSP-2023 organizing committee has invited three of the founding fathers of DSP to share with us their memories and experiences from those early days.
