sinyal sistemler lab ödevi yardım

x(t)=4u(t)+2sin (3 t)
Plot x(t) over the interval −4≤ t ≤4
Choose a stepsize that would help represent the signal accurately
and won’t cause aliasing.
Add grid lines to plot.
Label the axes appropriately.
Use title command and for x(t) write your name
y (t )=u(t )−1/2
Plot y(t) over the interval −2≤ t ≤2
Choose a stepsize that would help represent the signal accurately
and won’t cause aliasing.
Add grid lines to plot.
Label the axes appropriately.
Use title command and for y(t) write your surname
z [n]=4 cos(π n−2)
Plot z[n] over the interval −2≤ n ≤3
Add grid lines to plot.
Label the axes appropriately.
Use title command and for z[n] write your student number
f [n]=2sin (3 n)
Plot f [n] over the interval −3≤ n ≤3
Add grid lines to plot.
Label the axes appropriately.
Use title command and for f [n] write Homework2
Use axis command when ploting y(t), z[n] and f [n] to better show parts of the plot
that are at the very edge.
For example when plotting y(t) use axis([-2 2 -0.6 0.6]) ;
