To increase the power of analog signal , ADC can be improved by oversampling the input signal using the ADC and subjecting it to low -pass filtering.
Explanation:
An Analog signal is any continuous signal for which the time varying variable of the signal is a representation of some other time varying quantity.
The term analog signal usually electrical signals; however ,mechanical ,pneumatic, hydraulic, human speech, and other systems may also convey or be considered analog signals.
the accuracy of a low resolution ADC can be improved by oversampling the input signal using the ADC and subjecting it to low pass filtering, using a FIR filter to filter out the quantization noise and then decimating it.
