Solution:

Analog Filter	Digital Filter
Analog filters are used for filtering analog signals.	Digital filters are used for filtering digital sequences.
These filters are represented by linear differential equations	These filters are represented by linear difference equations
Implementing such filters requires resistors, inductors, and capacitors	Implementing such filters requires adders, subtractors, and delays
Filter representation is in terms of system components.	Digital filters are represented by the difference equation.
Difficult to design and then simulate because of several components	Significantly easy to design and simulate on software program
In such filters, there is no need for ADC, DAC, and DSP	These filters need high performance ADC, DAC, and DSP tools
