Note: The text ahead may make no sense whatsoever and tht’s pretty ironic since it’s all about logic….so if you’ll read ahead with a mind to understand something then think again

Was listening to a team mate of mine as he explained how the different musical instruments were mixed after recording using that signal mixing console. I asked him about adjusting the ‘bass’ and ‘treble’ levels and that what in God’s name were those two knobs for.
He launched in on a summarized explanation of how the low, deep notes like that of drums are controlled by playing with the ‘bass’ while high pitched, shrill sounds sometimes like that of guitars are smoothed over by the ‘treble’…As he carried on about how the inputs should just match the range set for any of these or other options…my mind flicked through the graphs and figures in Digital Signal Processing and the responses of various filters that we studied in them.
I smiled in spite of myself coz i had always loved those subjects that made logical sense
I remember i was in eternal awe of ‘Digital Logic Design’. A friend and I were making ‘4-way traffic signal’ for our DLD project and for the life of me i couldn’t understand how to convert the zeroes and ones into blinking , working lights…..until the journey from deciding logical states to truth tables, then equations and k-maps gave us our circuit…amazing!! the natural highs could be so damn exhilerating!.. The world of digital electronics has always mesmerized me because at the base of it lies the simple concept of presence or absence of a signal, very precisely timed. There is that software to hardware interfacing along with the tiny wonder machines called microprocessors and Digital signal processors that could do something as simple from sending a signal to an LED to acting as a complex speech transaltor… but at the base of these all lies the logic which tells when to or when not to send a signal.
In mathematics it’s a zero or one, in Computing a bit and in physical world a mere switch that turns on or off according to the defined patterns and that brings me to the wonder of having just the ‘right’ pattern…the proper sequence can regulate something as ordinary as accounting, tagging and shelfing of books to something as complex as booting of a pc…so at the apex of it or at the root of it all lies the sequence in which one command follows another.
I’m so keyed up now that i can’t even put together a decent and literarily respectable sentence to express my admiration for the magic, the tricks that logic and numbers are capable of…. I dont know if there is even a central idea to this post…it’s just a random set of words to pay my ode to virtual world of bits and frequencies that are making the companies run, control engineering the milk that goes into tetra packs, refreshing your monitor every fraction of a millisecond and ofcourse teaching u to be v careful and sure coz small mistakes in this environment mean big troubles in our world!!
