Rectangular pulse coming as trapezoid
显示 更早的评论
I have implemented a mechanism where I am feeding a rectangular pulsetrain to a multiport switch which should give a switcing sequence of rectangular pulses. However, I am getting the profile of the pulses as trapezoidal.
Solver Selection:
Is this because of the 'Fixed-Step' Solver (ode4-runge-Kutta)?
function block input:
output of function block:
(The code is written so V takes either 1 or 3 values)
Not sure why it's coming trapezoidal.
Output of Multiport switch:
Should be rectangular pulse, but coming trapezoidal.
What can be done in this case?

This is normal. The ideal perfect rectangular pulse requires two values (1 and 3) at the exact same time (e.g. t=0.2895). The output can't achieve that. There will be a tiny time difference between two consuctive outputs, as small as the time step (10e-6). The output curve connects two output points. It will show as trapezoidal when zooming in enough.
