1) Effect of the DFT Length on Spectral Analysis The signal to be analyzed in the spectral domain is given by xŒn D 1 2 sin.2f1n/ C sin.2f2n/ any explain about this method?

The quality of timing signals is essential for information transmission throughout telecommunication networks. Maximum Time Interval Error (MTIE), Allan deviation (ADEV), and time deviation (TDEV) are the parameters which give the information about the timing signal quality. Maximum Time Interval Error can be used for dimensioning the elastic buffers of the network circuitry located at the boundaries of areas timed by different time scales. ADEV and TDEV give the information about instability affecting the timing signal. The limit values of MTIE and TDEV for the particular types of clocks are defined and recommended in the telecommunication standards and requirements [1, 2, 3]. Computation of the parameter’s estimates and comparing them with the limits is an essential activity in the service and maintenance of telecommunications networks, so the obvious goal is to make the computation short in time.
