Rectangular pulses are formed according to fig. 1. If you do not set the value to the in elements, it works like a normal pulse generator pryamrugolnyh . If set to log in, you can modify the values a, b, c, d. Where:
a - step pulse, ms;
b - magnitude values of the momentum equal to the value c, ms;
c - determines the pulse amplitude, real number;
d - shift in phase in time, ms.
