Question

Please help me write a code for this in Matlab

T = 1 millisecond

Vm = 1 volt (amplitude voltage)

t = linspace(-T, 2*T, 3001)

The following pararameter is given

v(t) = Vm - (Vm/T)t for 0<= t <= T

0 elsewhere

I need to modify the vector v so that is represents a periodic function with a period T over this time period
(hint: it should look like a sawtooth), and plot v vs t over the range from -T to 2T.

Answer 1

T = 1;%millisecond
Vm = 1;%volt (amplitude voltage)
t = linspace(-T, 2*T, 3001);%To plot over the range -T to 2T
v = zeros(1, length(t));%Create a vector of size same as that of t
for i = 1:length(t)
    if t(i) >= 0 && t(i) <= T%If 0 <= t <= T
        v(i) = Vm - (Vm./T).*t(i);
    end
end

plot(t, v);
title('Plot: v vs t');
xlabel('Time period(t)');
ylabel('Voltage(v)');

OUTPUT:
