Write a script to generate the signal values for the figure above corresponding to equally-spaced time values ranging from 0 to 6*pi . Assign these time values to the variable Time. Assign the resulting voltage values to the variable signalVoltage. The sinusoidal function is given by the formula: Y=7sin(x) In order to model the clipping at plus or minus 5 Volts, you will need to replace any values of y that are greater than the threshold of 5 with the value 5. Similarly you will need to replace any values of y that are less than with the value -5

My attempt: Time= 0:6*pi Signal voltage = 7sin(time) Plot ( time, signal voltage) Signalvoltagelim([-5,5])

Don’t know what I am doing wrong. What in my script is wrong ?

在 MATLAB Online 中打开

time=linspace(0,6*pi,500);

Y=7*sin(time);

figure()

subplot(121),plot(time,Y);

ylim([-8 8]);

Y(Y>5)=5; % You can replace by any value, here I have consider 5

Y(Y<-5)=-5% You can replace by any value, here I have consider -5

Y = 1×500
