Description: design and implementation of a format conversion system on the Altera NIOS board(QUARTUS) which reads an analogue input, converts it into digital data, and then does the reverse conversion back into analogue format. This will be done by taking an analogue an analogue input using SPI MCP3202 12-Bit A/D converter to generate the digital data stream and then the digital data will be used to generate an analogue output using Analog Devices 8-bit SPI AD7303 D/A converter.

Description: c语言编写 示波器模拟软件, 具体看英文介绍。- This is an oscilloscope program written in c using the XForms library.
It uses the PC s parallel port for data input. The way it s done is as follows:
first data bit 1 is set to 1 then to 0 to enable the a-to-d converter
( ADC0801 ), then we read 4 bits of data from the multiplexer ( 74LS157 )
placed after the a-to-d, then a 1 is sent to the second data bit and the other
four bits of data are read. The circuit is setup as follows:
---------------------------------------------------------<---- Data bit 1
