Explain the advantages and disadvantages of FIR filters compared to IIR counterparts?
IIR filters are recursive and FIR filters are non-recursive. Also FIR filters are linear phase and IIR filters are not; several applications are sensitive to non-linear phase (communications, medical, etc). In implementation, IIR filters require fewer taps (smaller order) and thusly are easier to implement and have fewer zeros. Also FIR filters are always stable, while IIR filters can often become unstable in implementation. The previous answer is correct about delays.
What is noise filter?
noise filters are used in electronics and electric curcuts to reduce the the noise level which the electric switching generats sometimes the are single phase and there are three phase also the most used noise filters are ssr emc filters
What are the various types of filters that are employed in HVDC converter station?
There are various types of filters that are employed in HVDC converter station. These include high-voltage direct current and terminal stations.
What are the advantages of active filters over passive filters?
Active filters have three main advantages over passive filters:Inductors can be avoided. Passive filters without inductors cannot obtain a high Q (low damping), but with them are often large and expensive (at low frequencies), may have significant internal resistance, and may pick up surrounding electromagnetic signals.The shape of the response, the Q (Quality factor), and the tuned frequency can often be set easily by varying resistors, in some filters one parameter can be adjusted without affecting the others. Variable inductances for low frequency filters are not practical.The amplifier powering the filter can be used to buffer the filter from the electronic components it drives or is fed from, variations in which could otherwise significantly affect the shape of the frequency response.
Give the formula of state ohms law?
There is no equation for Ohm's Law. Ohm's Law simply tells us that, for ohmic or linear materials, the ratio of voltage to current is a constant.The equation you are, presumably, looking for is derived from the definition of the ohm, not from Ohm's Law, and that is resistance is voltage divided by current.
Difference between m-derived filters and constant k-filters?
in m derived impedance matching is possible but not in case of constant k filters. compared to constant k filter m derived filter has a sharp cutoff frequency. in k type the attenuation is not complete in the stop band.where as in the m derived just beyond the attenuation rises to max just after the cut off frequency. in m derived a capacitor and a inductor are taken in series at the output.
What is the procedure calculate the value of 'm' in m-derived filters?
m={1-[fc/f(infinity)]}^(1/2)fc={1/[Lc]^(1/2)} f(infinity)={fc/[(1-m^2)^(1/2)]}

What does Derived Property mean in maths?
i don't really know to be honest... i know that a derived property follows from a definition; (a definition is a minimum set of conditions needed to describe something)

What are the applications of m derived filters?
m-derivedfilters orm-typefilters are a type ofelectronic filter designed using theimagemethod. They were invented byOtto Zobel in the early 1920s.[1] This filter type was originally intended for use with telephonemultiplexing and was an improvement on the existingconstant k type filter.[2] The main problem being addressed was the need to achieve a better match of the filter into the terminating impedances.In general, all filters designed by the image method fail to give an exact match, but the m-typefilter is a big improvement with suitable choice of the parameter m. The m-typefilter section has a further advantage in that there is a rapid transition from thecut-off frequency of thepass band to apole ofattenuation just inside thestop band. Despite these advantages, there is a drawback with m-typefilters; at frequencies past the pole of attenuation, the response starts to rise again, and m-typeshave poor stop band rejection. For this reason, filters designed using m-typesections are often designed ascomposite filters with a mixture of k-typeand m-typesections and different values of m at different points to get the optimum performance from both types.[3]
Is the unit of speed a basic unit or a derived unit?
It is a derived unit. It measure distance traveled per unit of time. For example meter per second or m/s. Speed or velocity as it is sometimes called is derived from the units for distance and time.
