### Difference Equations and Causal SystemsThis lesson focuses on understanding the behavior of a causal system described by a difference equation and how to determine its output given a specific input.#### The Difference EquationThe system is defined by the following difference equation:\[ y[n] + y[n-2] = x[n] - 3x[n-1] \]For this configuration:- $ y[n] $ represents the output at time $ n $.- $ x[n] $ represents the input at time $ n $.The system is described as causal, meaning that $ x[n] = y[n] = 0 $ for all times $ n < 0 $.#### The InputThe input signal $ x[n] $ is specified as:\[ x[n] = \delta[n] + 2\delta[n-1] - 3\delta[n-2] \]Here, $ \delta[n] $ represents the discrete-time unit impulse function, which is defined as:\[ \delta[n] =\begin{cases} 1 & \text{if } n = 0 \\0 & \text{otherwise}\end{cases}\]#### Determining the OutputThe primary task is to determine the output $ y[n] $ for all $ n \geq 0 $. Given that “There are at most six distinct cases for $ n $,” the solution will involve sequentially solving the difference equation for different values of $ n $.Understanding these steps will enable you to solve for $ y[n] $ based on the given inputs and initial conditions of the system. Continue to the next sections for detailed calculations and interpretations for solving these kinds of equations.

Given a causal system: y[n]+y[n-2]=x[n]+3x[n-1] is such x[n]= δ[n]+2δ[n-1]-3δ[n-2] is applied to…

The causal system described by the difference equation y[n] + y[n – 2] = x[n] – 3x[n – 1] is such that x[n] = y[n] = 0 at all times n < 0. If the input x[n] = 8[n] + 28[n – 1] – 38[n – 2] | is applied to this system, determine the output y[n] for all n > 0. (There are at most six distinct cases for n.)
