PULSE(strtme,endtme)
Function whose value is 1.0 when the step time (i.e. variable t) is
greater than or equal to 'strtme' and less than or equal to 'endtme'.
That is,
PULSE = 1 when strtme <= t <= endtme.
Larger pulses can be achieved by multiplying PULSE times a constant.
E.g. 10 * PULSE(0,.001).
PULSE can be used to enable/disable an expression at different times
in the processing domain. For example,
fx = expr1*PULSE(-1000,0) + expr2*PULSE(0,1000);
