Processing an Input Analog Signal to get an Output Analog Signal
To process an input analog signal and get an output analog signal, the following blocks are required:
1. A/D Converter:
An analog-to-digital (A/D) converter is used to convert the input analog signal into a digital signal. The A/D converter samples the analog signal at regular intervals and converts each sample into a binary code that can be processed by a digital signal processor.
2. Digital Signal Processor:
A digital signal processor (DSP) is used to process the digital signal that has been converted from the analog signal by the A/D converter. The DSP uses algorithms to manipulate the digital signal and perform operations such as filtering, amplification, modulation, demodulation, and frequency analysis.
3. D/A Converter:
A digital-to-analog (D/A) converter is used to convert the processed digital signal back into an analog signal. The D/A converter takes the processed digital signal and reconstructs the original analog signal by converting the digital code back into an analog voltage.
4. Output Amplifier:
An output amplifier is used to amplify the output analog signal to the required level for driving the load.
Therefore, all the blocks mentioned above, i.e., A/D converter, digital signal processor, D/A converter, and output amplifier are essential for processing an input analog signal to get an output analog signal.
