How do you find the zero state response?
To find the zero state solution, take the Laplace Transform of the input with initial conditions=0 and solve for Xzs(s).
How do you find the impulse response of a system?
Given the system equation, you can find the impulse response just by feeding x[n] = δ[n] into the system. If the system is linear and time-invariant (terms we’ll define later), then you can use the impulse response to find the output for any input, using a method called convolution that we’ll learn in two weeks.
What are the three special properties that only LTI system follow?
What are the three special properties that only LTI systems follow? Explanation: Commutative property, Distributive property, Associative property are the unique properties of LTI systems which are special representations in terms of convolution and integrals.
What is the property of impulse response is called?
Explanation: Impulse response exhibits commutative property and it is given mathematically by the equation.
What is the commutative property of convolution?
Convolution obeys commutative, distributive (over addition) and associative properties in both continuous and discrete domains. Commutativity implies the system with input signal x(t) and impulse response h(t) and the other with input signal h(t) and impulse response x(t) both give the same output y(t).
What is the following type of system called Y N )= x n )+ y n 1?
What is the following type of system called? y[n] = x[n] + y[n-1]. thus obtaining an adder system.
Which of the following is the process of aliasing?
5. Which of the following is the process of ‘aliasing’? Explanation: Aliasing is defined as the phenomenon in which a high frequency component in the frequency spectrum of the signal takes the identity of a lower frequency component in the spectrum of the sampled signal.
What is the effect of aliasing?
In signal processing and related disciplines, aliasing is an effect that causes different signals to become indistinguishable (or aliases of one another) when sampled. It can also occur in spatially sampled signals (e.g. moiré patterns in digital images); this type of aliasing is called spatial aliasing.
How do you prevent aliasing?
The solution to prevent aliasing is to band limit the input signals—limiting all input signal components below one half of the analog to digital converter’s (ADC’s) sampling frequency. Band limiting is accomplished by using analog low-pass filters that are called anti-aliasing filters.
What is the Nyquist rate to avoid aliasing effect?
22050 Hz
