Answer to Question #164519 in MatLAB for passout

Question

If x1(n) = 5Sin(2πf1n) and x2(n) = 5Cos(2πf2n), then plot following signals in MATLAB  and attach screen shots of code and result 

(a) y1(n) = x1(n) + x2(n) (b) y2(n) = x1(n) – x2(n) 

note: f1 = f2 = Last two digits of your Registration Number

Hint: If last two digits of your registration number are 00 then take first two digits of your registration 

number as R (if last digits are say 05, then consider R = 5)

Answer 1

MATLAB CODE FOR y1(n)

x=linspace(0,2*pi,100);
y1=5*sin(10*pi*x)+5*cos(10*pi*x);
plot(x,y1)

OUTPUT SCREENSHOT:

(B)

MATLAB CODE FOR y2(n):

x=linspace(0,2*pi,100);
y2=5*sin(10*pi*x)-5*cos(10*pi*x);
plot(x,y2)

OUTPUT SCREENSHOT:
