Circuit Description DN308 unit consists of three circuit boards; Main board, and Key board. The Main board is the core of the unit whereas other boards are simple,1that is, the Key board has only contact switches . 4-1. Main Board Main Board circuit can be divided into several blocks, which are CPU block to control the whole system, DSP block to manipulate the audio signal, and analog block to control the input/output audio signal, and power amplifier. 4-1-1. CPU block Microprocessor(IC1) is powered by 3V DC/DC converter and controls the power of the DSP and Memory to save the batteries. It controls the LCD and check whether a key is pressed. Every time the CPU detects an event like key-in, it updates the contents of LCD and control the peripherals as the action of event which can be recording or playing back, etc. Mainly the important processes are to control DSP and Memory. Every Input from the Key board is connected to an input port of the CPU and it can be checked and activated by its falling edge. 4-1-2.
