how to generate below sawtooth pulse

and what is pulse number and how it generates in matlab

[Adam Danz]

Do you have the signal processing toolbox? If so, see sawtooth.

Have you searched the forum for an answer because this question has definitely been addressed.

Answer 1

[DGM]

The super-explicit way:

x = [0 1 1 2 3 3 4 5 5 6 7 7];
y = [0 1 0 0 1 0 0 1 0 0 1 0];
plot(x,y)

You could build those sequences any number of ways. Here's one:

xp = 0:2:7;
x = reshape(xp+[0 1 1].',1,[]);
y = reshape(xp+[0 1 0].',1,[]);
y = mod(y,2);

plot(x,y)

You could also use SPT tools:

x = linspace(0,7,1000);
y = max(sawtooth(pi*(x-1)),0);
plot(x,y)

Answer 2

Another approach using a logical threshold (specific to this waveform) —

t = linspace(0, 7, 500);
s = rem(t,2);
s = s.*(s<1);

figure
plot(t, s, 'LineWidth',2)
grid
axis([0  7.1    0  1.1])

what is pulse number i want sir

[Star Strider]

How do you define or calculate ‘pulse number’?

[nune pratyusha]

Pulse number is defined as the number of pulses in the dc

output voltage within one time period of the ac source voltage.

my dc voltage is 2v and ac source is sawtooth pulse .

[Star Strider]

‘Pulse number is defined as the number of pulses in the dc’

Please define ‘dc’. I doubt it means ‘direct current’ since this is is a pulse train.

[DGM]

It sounds like this has something to do with waveform synthesis (e.g. PWM). If that's the case, this waveform alone can't tell anyone anthing about pulse count. Pulse count would be something you would know only if you knew what the carrier frequency was in relation to the signal frequency. Since no other information is provided, I don't see how this question is answerable.

[Star Strider]

DGM — I completely agree!

[nune pratyusha]

but how to give pulse width and pulse period for above sawtooth signal

[Star Strider]

Two months!

In this instance, pulse width is one-half the period, and the period is the time between peaks. Several functions, such as findpeaks, islocalmax, islocalmin, and others are useful here.
