This is an excellent video. The filter examples provide context that was entirely lacking in my Digital Signals course.

I want to ask if you did assume the value of the piecewise function x[n]? what is your basis in setting those values to difference equation?

Determine the total solution of the following difference equation:
y(n)= 5y(n)-6y(n-2)+x(n)
when the forcing function, x(n)= 3^n and initial condition, y(-1)=2 & y(-2)=4.
Also, draw the difference equation using building blocks. sir answer please

how can you say that x[n-1] is lower frequency than x[n]. they are just samples in time domain

At 7:52 i dint understand the graph...y(n) was the average of 6 values so how come in graph we see many values....what is the graph a plot of?
