If i know the Transfer Function H(s)  of a system how can i find the frequency response of the same system?

Sorry to say but you will need a audio analyzer or oscilliscope to find the low end (drop off) and hi end (peak) of your system And the know how of reading both.

Use the general equation for Doppler effect from here( http://en.wikipedia.org/wiki/Doppler_effect ). f'/f = .86 and v0 =0 for you since the observer isn't moving. Note that since the frequency is lower that it must be moving away from you.

wave length = speed / frequency\n\n12 = 550 / f\nf = 550 / 12 = 45.8 Hz

In Control System theory analysis of processes can be made as a function of input to the system being controlled and the output which is the out come of the input.\n\nSo the in phsycology we can examine a person capacity by observing a persons response to a stimulus. The Input is the stimulus and the person is the system and the response is the output.\nThis can be represented  by a diagram.\nThe system is drawn as a block with represents what is in the sytem. So if we know what the out put and the out put is we can determine what makes the system tick.\n\nThis is done by taking the ratio of the input to out put.This ratio is called transfer function. This transfer function is usually expressed as differential equations. These equations can be solved to determine the response of the system.\nBlock diagrams can be used as a topographical tool of analysis.

This requires the use of doppler shift formula for a moving source and stationary observer:\n\nf = f0 ( v / ( v + u ) )\n\nf0 = actual frequency = 5\nv = speed of wave = 20\nu = relative velocity of source away from observer = -10\n(since travelling toward)\n\nf = observed frequency = 10 Hz\n\nNow velocity = v = fl = frequency * wavelength\n\nso wavlength l = v / f = 20 / 10 = 2m

If we assume SHM, then\n\n(a) for a given amplitude A, the max velocity and max acceleration is greater for higher frequency sounds, because SHM is given by the following equations:\n\ny(t) = Asin(2πft + γ) where γ is a phase factor\nv(t) = dy/dt = 2πfAcos(2πft + γ)\na(t) = dv/dt = -(2πf)²Asin(2πft + γ)\n\n(b) For A = 1.0 x 10^-8 m and f = 20.0 Hz\n\nv(max) = 2πfA = 1.26 x 10^-6 m/s\na(max) = -(2πf)²A = - 1.58 x 10^-4 m/s^2

I believe you are talking about system type number?\n\nIt is the number of integrators (1/s) in the plant transfer function.\n\neg: the number of "s=0" roots in the denominator\n\nKnowing the system type, you can then easily calculate steady state error in the standard form closed-loop system for step, ramp, and parabolic inputs.

T = 2pisqrt(l/g)\nl = g(T/(2pi))^2 = 9.80(1.0/(2pi))^2 = 0.25 m\n\n(The object's weight is irrelevant for small oscillations.)

I hope, you mean frequency for pitch. \n\nThe frequency “n” is given by the formula, n = (1/2pi) x root of (k/m)\n\nk is the coefficient of stiffness of the spring and m is the mass attached to it.\n\nBy measuring the extension of length of the spring for a given force, the force per unit length gives the value of k.

You need to have recorded the power over a range of frequencies and ploted the Output over the Input. If the chirp signal can be extrapolated into its freqency components possibly you can compare the output to this, otherwise a new set of data points are required.

One of the most frequently used is E=IR    ;E =voltage    I=current   R= resistance. U can change this every way depending on the unknown.\n    Good luck

Need more detail.  Analog or digital?  Cutoff frequency?  Out of band rejection?  Is there a constraint on number of orders?  Matlab has built in functions to do filter design.  \n\nSomething a simple as a suitable capacitor will block low frequency.
