frequency

here i am, taking a short little break from tutorial mugging(surprised). it is a seemingly never-ending race to keep up with tutorials. im simply wondering how do some people keep up work with lecture pace. either they have to mug like mad, is PRO-ly smart(i know a few) or has just 48hrs a day.

anyway, that is not the idea for today. i shall be talking about digital content and distribution systems aka DCSDS. in particular, frequencies.
as everyone would know, in order to receive effective communication, the receiver must be the same frequency as that of the transmitter.
for radio and all sorts of mechanical devices, their frequency is readily set to operational levels and are usually not easily subjected to changes, be it sudden or gradual.
however, for humans, in particular one's friends, their frequencies tend to oscillate wildly and immensely. previously, a common frequency was easily determined and obtained for my friend and i, communication flourished easily spite of inherent and apparent similarities, a common frequency has never since been re-achieved. despite scanning the whole limits of possible frequency, the matching receiver frequency has not been found. maybe i have moved into a range of possible frequencies vastly different and that it has been the case for my friend as well, but it simply matters much.
while some have gone on and found their own optimal frequency ranges, contact is still possible due the presence of overlapping frequency channel. acting on both transmitter and receiver.

so it is my wish that i can re-find that optimal frequency range that is common.
