What’s Involved and What We Support

The analog signal can be the input and/or the output interface to any design. The analog input signal chain receives its analog signals from keyboards, sensors, accelerometers, etc. This input signal is then conditioned or filtered via an amplifier to remove any unwanted noise or to amplify the input signal. The signal is then converted to the digital realm through an analog-to-digital (A/D) converter. CPUs are now able to understand the digital information supplied by the A/D converter.

The opposite function is performed in the analog output signal chain. The digital signal from a CPU is converted to an analog signal by either a digital-to-analog (D/A) converter or from an on-chip D/A on the microprocessor/DSP. This input signal is then conditioned or filtered via an amplifier to remove any unwanted noise or to amplify the signal. The analog signal is then outputted to the analog world via a speaker, motor/fan, LED etc.
