x = linspace(1, 10*pi, 200);
y = sin(x);
y(60:90) = y(60:90) + 1;
y(120:180) = y(120:180) - 1;
yOrig = y;
limit = 0.2;
dy = [0, diff(y)];
jump = strfind(abs(dy) > limit, [false, true, false]);
for ijump = 1:numel(jump)
k = jump(ijump);
y(k+1:end) = y(k+1:end) - dy(k+1);
end
figure
axes('NextPlot', 'add')
plot(x, yOrig, '-r', x, y, 'bo')
y2 = lowpass(y, 30, 200);
plot(x, y2, 'c+')

I guess those were just some parameters to cause a chunk of the waveform to shift by a reasonable amount.
