ADC-DAC

Here we have written a code on CCS to generate  Sawtooth, Triangular and Sinusoidal waveforms and observe the output on the DSO. Analog-to-Digital Conversion (ADC) and Digital-to-Analog Conversion (DAC) are the processes that allow digital computers to use and output these everyday signals. The DSP board that we have used had a 4 channel DAC and 2 channel ADC. We gave a variable voltage to one channel of the ADC via a potentiometer (the voltage was positive) and then using the digital value we gave it to the DAC and observed the output on the DSO.

  1. Good that your college has made it's custom DSP board!

  2. So you observed 3 waveforms on DSO, great!

  3. ADC and DAC are observed in so many real life products!

  4. The analog signals are generated at the sampling frequency applied to the DAC clock

  5. Now, headphone jacks are removed from phones and headphones are directly connected to the charging port, changing the technology from Analog to Digital!
