Hi enjoykin4,
At the moment the conditions of my wife are stationary and require my continued presence so I can only dedicate myself to the theory of LRLs, but as I said I am very interested to infrared rays, by comparing the signal provided by my LRL and the one provided by a infrared system it could be possible a sort of discrimination. I am preparing a similar system to the pulse induction, where there is a pulse transmitted by an infrared LED and a receiving part, another infrared LED, a kind of infrared radars. Soon I'll post the schematic so someone can experience it. As for the impulse of which you speak I have some experience with the construction of electronic musical instruments, electronic organs in particular, according to the Fourier analysis the square wave contains only odd harmonics of decreasing amplitude and for obtaining a sawtooth wave is necessary to add to square wave his higher octaves with decreasing amplitude. Thus only with square waves (easily available with frequency dividers) was possible to have a sound with odd and even harmonics. As a boy I also repaired the radios and I used a square wave generator (about 1000Hz), a signal tracer useful to inject the signal even in the high frequency stages as the harmonics easily arrived in the Mhz range.
Best Regards
