Answer 2

The Nyquist criterion is difficult since A) There are abrupt transitions obtained at edges of the bands

• The Nyquist criterion is used in the design of a dynamic system. Feedback is an important process in the development of dynamic control systems. Since the development of the system consists of many steps, it is important to have a feedback mechanism to monitor the accuracy of the systems.  
• It consists of a loop in which the electrical signals can be monitored.  
• Since the system is highly sensitive to inputs, there are abrupt transitions in the edges of the end. This is the main problems encountered by engineers in using the Nyquist criterion.
