Abstract:
In this project we attempt to design a simple ADC/DAC card which can be easily interfaced with 8085 microprocessor kit for Data Acquisition(DAQ) purposes. We extent our work by designing a pcb

APPLICATION:
Commerical ADC/DAC cards can cost hundreds of dollars, not viable for teaching purposes. This ADC/DAC card, which is much cheaper can be used ....etc

The project is designed to automatically operate an electric bell several times as required in an educational institution like school or college. It overcomes the difficulties of switching the bell on/off manually. This proposed system has an inbuilt real time clock (RTC) to keep a track of the time and thus to switch on/off the load accordingly.

The project uses a real time clock (RTC DS1307) interfaced with the microcontroller of the 8051 family. While the set time equals to the real time, the microcontroller gives command to the correspon ....etc

The are many cool sensors available now a days, ranging from IR distance sensor modules, accelerometers, humidity sensors, temperature sensors and many many more(gas sensors, alcohol sensor, motion sensors, touch screens). Many of these are analog in nature. That means they give a voltage output that varies directly (and linearly) with the sensed quantity. For example in LM35 temperature sensor, the output voltage is 10mV per degree centigrade. That means if output is 300mV then the temperature is 30 degrees. In this tutorial we will learn how ....etc

DAC and ADC converters

-Data Converter impacts the factor for the performance of the overall radio design
-Requirements: very high sampling rates, high number of effective quantization bits, an operating bandwidth of several Ghz, a large spurious-free dynamic range, a reasonable price
-DAC and ADC converters
-Sampling and Quantization
-Nyquist Zones
-Aliasing
-Bandpass filtering uses image to translate bandpass signals to baseband
-Errors occurs in Quantization
-Quantization Noise
-O ....etc

What is DAC? Digital to analog converter (DAC) is used to get analog voltage corresponding to an input digital data. Data in binary digital form can be converted to corresponding analog form by using a R-2R ladder (binary weighted resistor) network and a summing amplifier. It is more common and practical. Below is the circuit and output simulated waveform of R-2R ladder network DAC. This circuit also uses an op amp (741) summing amplifier circuit.
You can learn how to build a Digital to Analog converter using the simple technique explained in ....etc
