BL0306, Digital Echo

The BL0306 is a digital ECHO IC fabricated with silicon gate CMOS technology .

The BL0306 converts an input analog signal to a digital signal and writes it into a memory IC,After a delay it reads out the digital signal from the memory IC and then converts to an analog signal again.

Lower noise and d
