Random signals are used to test dynamic response statistically for very small amplitudes and time-duration. How it can be avoided? Aliasing refers to an effect due to which different signals become indistinguishable. It also refers to distortion in the reconstructed signal when it is reconstructed from the original continuous signal. To avoid aliasing we can simply filter out the high frequency components of the signal by using anti-aliasing filter like optical anti-aliasing filter.
Define one-sided and two-sided Z-transform. What is region of convergence ROC? Define Z-transform of unit step signal. What are the different methods available for inverse Zs-transform? When the z-domain transfer function of the system can be directly obtained from s-domain transfer function? When input is an Impulse sampled signal.
What is an embedded system? An embedded system is a special purpose computer system which is completely encapsulated by device it control. It is a programmed hardware device in which the hardware chip is programmed with specific function. It is a combination of hardware and software. What are the characteristics of embedded system? The Characteristics of the embedded systems are as follows-. What is digital signal controller?
