In frequency domain the relative stability of a system can be studied from Nyquist plot. The relative stability of the system is given by closeness of polar plot to -1 to j0 point. As the polar plot gets closer to.

The term stability refers to the stable working condition of a control system. In a stable system, the response or output is predictable, finite and stable for a given input or for any changes in system parameters. The output is.

Discrete time Fourier Transform (DFFT) of an aperiodic signal is continuous function of Ω and is periodic with period 2π. LTI discrete time systems can be analysed using DTFT, if input signals are DTF transformable and if system is stable..

This part of Z – Transform consists of problems of 2 marks each and are little more complex than the problem of (Part – I). A good number of problems are considered with elaborate solutions. Download MCQs from here

The time response of the system is the output of the closed loop system as a function of time. The output or response in s-domain, C(s) is the product of the transfer function and the input, R(s). The time response.

In a system when the output quantity is controlled by varying the input quantity, the system is called control system. An open loop system does not automatically correct the variation in its output. The open loop systems are modified as.

For analysis of LTI systems, transform techniques have been important tool. For CTLTI Systems Laplace transform is an extension of Fourier Transform. For analysis of DTLTI Systems z – transform plays the same role as Laplace transform does for CTLTI.

This part forms the basic of signals and systems. Signals can be classified as continuous time or discrete time, analog or digital, periodic or aperiodic, energy signals or power signals, deterministic or random signals etc. Similarly, systems can be classified.

In part – I, We have seen Periodic Signals as sum of sinusoids or exponentials (Fourier Series). In this part we deal with aperiodic signals which are represented by Fourier Integral. An aperiodic signals may be regarded as periodic signal.
