%unit impule

%unit step

%ranp

%exponential

%sine and cosine

t=(-1:0.1:1);

a=(-10:0.1:10);

r=(-1:0.1:1);

impule = t==0;

subplot(4,4,1:2);

stem(t,impule);

title('Unit Impulse');

step = t>=0;

subplot(4,4,3:4);

stem(t,step);

title('unit step');

ramp = r;

subplot(4,4,5:6);

stem(r,ramp);

title('ramp');

expn = exp(t);

subplot(4,4,7:8);

stem(t,expn);

title('exponential');

x=sin(a);

subplot(4,4,9:12);

stem(a,x);

title('Sine Wave');

y=cos(a);

subplot(4,4,13:16);

stem(a,y);

title('cosine wave');
