The ANALOG FILTER used in analog circuits.The DIGITAL FILTER USED IN DIGITAL circuits.
*in analog filters i/p n o/p r continous time signal. *in digital filters i/p n o/p r discrete time signa * implementatn ov analog filters is carried out usng passive n actv components *digital filters r implemented on a digital or micro computer usng DSP integrated ckts.3 basic element such as adder,multiplier n delay elements r used in digital filters
transducer convert one energy to other energy .now in analog transducer it convert energy use of analog signal and digital it converts use og digital signal
Digital sensors produce digital output (0 or 1) which can be easy to communicate directly with a microcontroller. Analog sensors provide analog outputs which one must firstly digitize to sense the level. Analog sensors are generally more accurate.
Analog is displayed in a clock like instrument digital is shoun in numbers
Analog signals are continuous while digital signals are discrete
Analog would be like a sliderule which is based on logarithms. Digital would be like a calculator.

The main difference between these scales it that the digital will give a more accurate and easier to read reading than figuring it out with the lines between the numbers the analog scale. However, the digital scale requires and battery and the analog does not.

Difference between analog and digital filter are :Digital filters:It operates on the digital samples of the signals.These kinds of filters are defined using linear difference equations.While implementing the digital filters in hardware or software we need adders, subtractors, delays, etc which are classified under digital logic components.4. For stability and causality,the poles of the transfer function should lie inside the unit circle in z-plane. . Analog filters:analog filters works on analog signals or the so called actual signals.It is defined by linear differential equations.While implementing the analog filters in hardware or software simulation, electrical components like resistors, capacitors and inductors are used.4. For stability and causality, the poles should lie on the left half of s-plane.
Digital signals permit greater transmission of data over analog signals. The URL http://telecom.hellodirect.com/docs/Tutorials/AnalogVsDigital.1.051501.asp has quite a bit of useful information on the differences between analog and digital broadcasting
The basic difference is that in analog modulation the modulating signal is analog signal and in digital modulation it is in digital form.

Analog can reach higher speeds.
analog is a D'arsonal movement (an indicator needle over a scaled background) and a digital meter is a LCD display that has no movement
