Re: pwm
you can control the motor speed by controlling the average of the input voltage(dc component), and this is exactly what you are doing through the PWM. as you can control the average of the PWM signal by controlling the PWM duty cycle.
increasing the PWM duty cycle means that you...

hi
the following is a matlab code for 16QAM by a small modification it will be for 4QAM
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% QAM %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

M=16;
L=sqrt(M);
Eav=4;
data=randint(1,nbit);
k=sqrt((3*Eav)/(2*(M-1)));

hi to all
1)FDMA: frequency division multiple access and in this technique the total bandwidth is divided between users,i.e. all users send the data on the same time but different frequencies. FDM is the same but the only difference is in FDM we have one transmitter and...
