Analog and Digital Filters
This means the digital filter can easily be changed without affecting the circuitry ( hardware) An analog filter can only be changed by redesigning the filter circuit 2

WINDER, S. ( ). Analog and Digital Filter Design ( nd ed.)
Analog voltage controlled filters are frequently quite noisy, yet the noise itself is not terribly objectionable In contrast, the effects of quantization of digital audio
making digital filters sound analog
Digital filters are a very important part of DSP Digital vs Analog Filtering * High Accuracy * Linear Phase (FIR Filters) performance than analog filters
DSP Digital filters
Digital filters ➢ are implemented using a digital computer or special purpose digital hardware ➢ A digital filter, in general, is a computational process,
SigSys Lect Introduction to Filters
Filtering may be applied to signals which are then transformed back to the analogue domain using a digital to analogue convertor or worked with entirely in the

Let's compare the two filters blow-by-blow As shown in (a) and (b) the analog filter has a 6 ripple in the passband while the digital filter is
The key difference between analog and digital filters is that instead of calculating resistor capacitor and inductor values for an analog filter coefficient
Analog filters are created from circuit elements including resistors inductors capacitors and operational amplifiers Digital filters are
An analog filter uses analog electronic circuits made up from components such as resistors capacitors and op amps to produce the required filtering effect
In modern electronic product design one can often make a choice between analogue and digital signal processing With analogue processing the filtering and
