PPT-Digital-to-Analog & Analog-to-Digital Conversion

BJ Furman 21APR2016 DAC and ADC DigitaltoAnalog Conversion DAC Converts a binary value to a scaled analog voltage Used for controlling systems that require an analog input DC servo motor. We have no digital cable boxes that will work on digital cable tv No digital cable box is available Digital cable descrambler and digital cable box will be available someday At this time no digital cable tv box is available Look for digital cable de Introduction to Mechatronics.

Why is conversion needed?. Most signals in the world are analogue.. Microprocessors and most computers computers use digital signals.. Analogue to Digital Converters (ADCs) change analogue signals to digital signals that are then used by the microprocessor.. Digital Inputs and outputs have only two states: 0 or 1.. Examples:. Push Button. Pressure Switch. Temperature Switch. Limit Switch. Analog Inputs and Outputs. Analog Inputs and Outputs have a continuous range of values representing some quantity..

LADDER-NETWORK CONVERSION. Another popular method of analog-to-digital conversion uses a ladder network. along with counter and comparator circuits (see Fig. 17.15). A digital counter advances. from a zero count while a ladder network driven by the counter outputs a staircase.
