PT2399 Overview
The PT2399 is a single chip echo processor IC utilizing CMOS technology. Which accept analog audio input signal, a high sample rate ADC transfer the analog signal into a bit stream then storage to internal 44Kbit RAM, after processing the bit stream will de-modulate by DAC and low pass filter. Overall delay time is determined by internal VCO clock frequency, and user can easy to change the VCO frequency by changing...
