Program to generate FM Signal and Analyze the effect of increasing modulation index for each modulation technique.

// FM --> Frequency Modulation

Ac=10;
Am=10;
wm=2*%pi*25;
wc=2*%pi*400;
t=[1:0.0002:1.1];

m=Am*cos(wm*t);
c=Ac*cos(wc*t);


subplot(5,1,1);
mf=10;
Sam1=Ac*cos(wc.*t+(mf)*sin(wm.*t));
plot(t,Sam1,'red');
legend('m=10');

mf=12;
subplot(5,1,2);
Sam=Ac*cos(wc.*t+mf*sin(wm.*t));
plot(t,Sam ,'blue');
legend('m=12');
xlabel('Time');
ylabel('Amplitude');


subplot(5,1,3);
mf=15;
Sam=Ac*cos(wc.*t+(mf)*sin(wm.*t));
plot(t,Sam,'black');
legend('m=15');


subplot(5,1,4);
mf=20;
Sam=Ac*cos(wc.*t+(mf+20)*sin(wm.*t));
plot(t,Sam,'green');
legend('m=20');

subplot(5,1,5);
mf=15;
Sam1=Ac*cos(wc.*t+(mf)*sin(wm.*t));
plot(t,m,'black',t,c,'green',t,Sam1,'blue');
legend('m=15');




// Output

    Econometrics can be challenging because it combines economic theory, mathematics, statistics, and data interpretation. Students often need extra guidance when working with regression models, hypothesis testing, and statistical results. econometrics assignment help can help simplify these areas by providing structured explanations and practical examples. Understanding the reasoning behind calculations is more valuable than simply finding an answer. With consistent practice and useful academic support, students can improve their analytical abilities and approach econometrics coursework with greater confidence.

  Simulate BASK or ASK technique using Scilab. // BASK or ASK --> Binary Amplitude Shift Keying   t=[ 0 : 0.02 : 5 * %pi ]; wc= 7 ; A= 0.5 ;  Vm= squarewave (t, 30 );  // The second parameter in the squarewave function is the percent of the period in which the // signal is positive.  Vc=A/ 2. * cos (wc.*t); Va=( 1 +Vm).*(Vc);  subplot( 3 , 1 , 1 ); plot(t,Vm, 'black' );  subplot( 3 , 1 , 2 ); plot(t,Vc, 'black' );  subplot( 3 , 1 , 3 ); plot(t,Va, 'black' ); // Output                               BASK or ASK --> Binary Amplitude Shift Keying
