Hi feldoh, Thank you for your input. If a square wave is input, that is all odd orders, what if a signal that had even and odd were input, still a convolution and not perfect sinewave? Thanks

Hi brewnog, Yes, the second sentence of my first post shows the definition of a sinewave from a book published in 1976. Fundamentally, we all know what a sinewave is, but to match up with the sin button on a calculator, or sin tables that have been published, the phasor has to be rotating...

Thanks uart and brewnog. I appreciate your responses and yet, I am still reaching deeper as follows: Along these lines, can someone explan if an RC filter, for example, (what ever filter actually, bandpass, blah blah) when it decodes from a complex waveform, a waveform that it is "tuned" to...

Hi vk6kro, Thank you for replying. You bring up an interesting thing about filters. The whole point I am dealing with I think is that there are almost no "circular" sinewaves in music. (ie the one that gives you the numbers in the sine tables or the one function designed into...

First, as an electronic tech, 30+years, I learned about a sinewave, definition: a wave that can be expressed as the sine of a linear function of time, space or both. Key here to me is the word expressed. The sinewave I learned about was a phasor going anti-clockwise in a circle...

Thank you sachinism for your reply. given the definition of a sinewave in the previous post, then I assume that a linear function means say degrees, seconds, etc. So, a sinewave as I learned in electronics, developed from a phasor in a circle, is not the only wave that can be described...

I am not an expert in math, but as an electronics tech we use sinewaves all the time. I understand how it is derived from a circle well enough ( a phasor rotating about a circle). And that makes sense as that is how electricity can be generated due to the orientation of the generator...
