Question

Please show commands and explain how to plot. Thank you.

7. Lab Assignments 7. 1 Plot y-cos(2x π x 60x t) + 0.2 sin(2x π x 1 80x ) + 0. I sin(2x π x 300 x ) , for 0ss0.05s. Sampling step should not be greater than 0.02 ms. 7.2 Replace the "Fen" in Fig4from sin(u) to cos(2u) and do the simulation again and report your simulation result. 7.3 Write the branch currents down for the circuit shown in Fig. 7. Print out your simulation results and compare them with your circuit analysis. When you're finished, hand it in with your completed data table given below. Branch currents R1 R2 R3 & R4

Answer 1

R CODE NEEDED FOR THE PLOT

#taking sampling size as 0.01 ms

#0.02ms is .00002 seconds
x<-seq(0,0.05,.00001)
y<-cos(2*pi*60*x)+0.2*sin(2*pi*180*x)+0.1*sin(2*pi*300*x)
plot(x,y)
