PL-390 Functional Block Diagram
PL-390 is using DSP si4734 Microchips (from Silicon Labs in
USA) to digitalize the analog AM/FM broadcasting signal base
on the modern software technology and radio principles. It can
highly improve on radio's sensitivity, selectivity, S/N ratio and
anti-interference.
