The given waveform is a piecewise smooth function, and it can be constructed as follows:
t = 0:0.1:2000;
% Defining the Segments
x1 = 0.07*(t < 200); % segment 1
x2 = ((0.37 - 0.07)/( 600 - 200)*t - 0.08).*(( 200 <= t) & (t < 600)); % segment 2
x3 = 0.37*((600 <= t) & (t < 800)); % segment 3
x4 = ((0.70 - 0.37)/(1200 - 800)*t - 0.29).*(( 800 <= t) & (t < 1200)); % segment 4
x5 = 0.70*((1200 <= t) & (t < 1800)); % segment 5
x6 = ((0.00 - 0.70)/(2000 - 1800)*t + 7.00).*((1800 <= t) & (t < 2000)); % segment 6
% Combining all segments and plotting it
x = x1 + x2 + x3 + x4 + x5 + x6;
plot(t, x, 'linewidth', 1.5)
ylim([0 1]), grid on, xlabel('t'), ylabel('x(t)'), title('Piecewise Smooth Function')
