Σύνοψη

This project is intended to lay the foundations for the development of a high sampling rate Data Acquisition System to capture analogue signals (sound), convert them into binary 8-bit samples and store them on an auxiliary memory device such as a floppy disk or the hard disk of the IBM PC. Then using a reverse procedure, the stored 8-bit binary samples can be recalled and recovered back to analog signals.
The conversion frequency can be adjusted with the variable 10K resistor. For best performance a value of 6.8 K 0 is selected which corresponds to a conversion time of about 2us.
The project is divided into two main parts: hardware and software. The first part deals with the hardware design of the system. Although many techniques of designing 2 layer-PCB Boards were studied using suitable software from the market. a PreFabricated ISA - XT Slot Board was selected for fast troubleshooting and quick correction of possible faults. The second part deals with the software; 2 simple programs using the Turbo Pascal V 7.0 were written to provide the control signals (ADC and DAC) and storage of the captured data into a file on the hard disk or floppy disk.
