How to generate a few timing signals as shown below?

Thanks in advance!

Check out

rectpuls(t,w); % w controls width of it; need to synthesize time vector

and

tripuls(T,w,1); % Use value of 1 for s input to get shape for middle signal

For the top and bottom signals, you will have to do sums of a couple different rectpuls outputs. Here is an example

t = linspace(-125,125,2501);
% Just remember, you shift time so for example
% delta(t-2) shifts the shape (line with x) like:
%   x                        x
% __|______ impulse --> _____|___
%   0  2                  0  2
%   (time)                (time)
Vgs_resetProgram = -rectpuls(t+60,20);
Vgs_setProgram = rectpuls(t-40,20);
Vgs = Vgs_resetProgram + Vgs_setProgram;
Vds_resetRead = tripuls(t+10,20,1);
Vds_setRead = tripuls(t-90,20,1);
Vds = Vds_resetRead + Vds_setRead;
IMT_State = rectpuls(t-90,20);
figure('Name','Timing Signal Example');
subplot(3,1,1); plot(t,Vgs,'r-'); 
ylabel('V_{GS}','FontName','Arial','Color','k');
subplot(3,1,2); plot(t,Vds,'g-'); 
ylabel('V_{DS}','FontName','Arial','Color','k');
subplot(3,1,3); plot(t,IMT_State,'b-'); 
ylabel('IMT State','FontName','Arial','Color','k');
suptitle('Timing Signal Example');
xlabel('Time','Color','k','FontName','Arial','FontWeight','bold');

Thanks a lot! Works great.
