endobj EXPERIMENT 4 Digital-to-Analog Conversion A. In this experiment we are going to setup an ADC circuit using ADC0804 converter, resistors, capacitor and 5v power supply. The analog signal is described in terms of amplitude, phase, and frequency. The 4-bit number is used as input to buffer circuits (the rectangular blocks labelled ‘1’). Dual-Slope converter – this type of converter uses an op-amp integrator, comparator, digital control circuits, and digital clock circuits, along with a counter to generate the binary or BCD value from an analog … The reverse operation is performed by a digital-to-analog converter (DAC). Download Full PDF Package. There are several DAC architectures; the suitability of a DAC for a particular application is determined by figures of merit including: resolution, maximum sampling frequency and others. In practice, due to the variations in the logic HIGH voltage levels, all the steps will not have the same size. Digital to Analog Converter (DAC) Lab Assignment: Students use the electronic circuit simulation packages available [1,2] in the computer lab to analyze the binary weighted and R-2R Ladder type circuits. • Relation between analog signal and digital equivalent n a i re i f i1 V b 2− V = =×∑ • AD conversion – Va-> bi (encoder) ex) Transducer interface Experiment #4: Basic Digital to Analog Conversion Basic Analog and Digital Student Guide Version 1.0 • Page 65 Build a Resistive Ladder Network Digital to analog conversion (D/A conversion) is, for the most part, the reverse of A/D conversion. 0000134138 00000 n %%EOF ANALOG TO DIGITAL CONVERTER. We hear music as a Introduction Digital-to-analog converters are normally chosen for application within a given system on the basis of their resolution and accuracy, which, in turn, is generally determined by N, the number of input bits of the converter.The following is a listing and definitions of key DAC terms and specifications: Resolution. Since the real world is analog, but the computer world is binary, we need to be able to convert signals between the two. 0000051760 00000 n A DAC may be characterized by any of the following parameters: the number of bits used, the output voltage/current range(s), settling time, and linearities. 0000001301 00000 n The original analog waveform Introduction Our perceptual world is largely based on analog inputs.

This circuit will be used again in Experiment 11 as the core of an analog to digital converter (ADC). The original recording has both continuous time and continuous valued the final digital signal will have both discrete time and discrete value. To build a D-A converter and an A-D converter. Digital to Analog Converter (DAC) Digital to Analog Converter (DAC) is a device that transforms digital data into an analog signal. Lab 5: Analog-to-Digital Converter (ADC) 1. This paper. Analog to Digital (A-D) and Digital to Analog (D-A) Conversion Goals To become familiar with digitally represented data. 281 0 obj <> endobj EXPERIMENT 4 Digital-to-Analog Conversion A. In this experiment we are going to setup an ADC circuit using ADC0804 converter, resistors, capacitor and 5v power supply. The analog signal is described in terms of amplitude, phase, and frequency. The 4-bit number is used as input to buffer circuits (the rectangular blocks labelled ‘1’). Dual-Slope converter – this type of converter uses an op-amp integrator, comparator, digital control circuits, and digital clock circuits, along with a counter to generate the binary or BCD value from an analog … The reverse operation is performed by a digital-to-analog converter (DAC). Download Full PDF Package. There are several DAC architectures; the suitability of a DAC for a particular application is determined by figures of merit including: resolution, maximum sampling frequency and others. In practice, due to the variations in the logic HIGH voltage levels, all the steps will not have the same size. Digital to Analog Converter (DAC) Lab Assignment: Students use the electronic circuit simulation packages available [1,2] in the computer lab to analyze the binary weighted and R-2R Ladder type circuits. • Relation between analog signal and digital equivalent n a i re i f i1 V b 2− V = =×∑ • AD conversion – Va-> bi (encoder) ex) Transducer interface Experiment #4: Basic Digital to Analog Conversion Basic Analog and Digital Student Guide Version 1.0 • Page 65 Build a Resistive Ladder Network Digital to analog conversion (D/A conversion) is, for the most part, the reverse of A/D conversion. 0000134138 00000 n %%EOF ANALOG TO DIGITAL CONVERTER. We hear music as a Introduction Digital-to-analog converters are normally chosen for application within a given system on the basis of their resolution and accuracy, which, in turn, is generally determined by N, the number of input bits of the converter.The following is a listing and definitions of key DAC terms and specifications: Resolution. Since the real world is analog, but the computer world is binary, we need to be able to convert signals between the two. 0000051760 00000 n A DAC may be characterized by any of the following parameters: the number of bits used, the output voltage/current range(s), settling time, and linearities. 0000001301 00000 n The original analog waveform Introduction Our perceptual world is largely based on analog inputs. The resolution of a DAC is given by the number of bits, N. ELEC 2010 Laboratory Manual Experiment 11 Design Project Specifications Page 1 of 5 Revised June 14, 2001 Experiment 11: Analog-to-Digital Converter (ADC) Design Project NOTE: This is a two-week experiment worth double credit (100 total points). Objectives The objective of this lab is to show how the analog-to-digital converter (ADC, A/D, or A-to-D) chip can be used to convert an analog input signal to a digital data. Figure El-I Ideal waveform of analog to digital converter 0000007903 00000 n <]>> According to the Nyquist-Shannon sampling theorem, any sampled data can be reconstructed perfectly with bandwidth and Nyquist criteria. The higher resolution and the smaller converting time make the chip more expensive. The output of the A/D converter will then be input into the same DAC constructed in Experiment #9. Experiment #3: Basic Analog to Digital Conversion Basic Analog and Digital Student Guide Version 1.0 • Page 43 The ADC0831 Integrated Circuit - An 8-bit Analog to Digital Converter The ADC0831 is an integrated circuit referred to as an 8-bit analog to digital converter (A/D converter… A DAC can reconstruct sampled data into an analog signal with precision. xref Digital-to-Analog Converter Circuit – Binary-Weighted Resistors Method Graph.
