书籍 Optical+Communication+Theory+and+Techniques
Since the advent of optical communications, a great technological effort has
been devoted to the exploitation of the huge bandwidth of optical fibers. Start-
ing from a few Mb/s single channel systems, a fast and constant technological
development has led to the actual 10 Gb/s per channel dense wave ...

This programme is to control DC motor in a certain speed using PWM.
The target speed is "r", it is the speed in 1s.
The sample rate is 0.1s, so the actual speed target is "rc"=r/10.
The "r" and "rc" are integer, and the range of "r" is from 50 to 100.
Keep rc=r/10!!!
The array "speed1" and "speed2" ...
