Can some Briefly explain the significance of the different  waveforms?

You may be talkig about a square, sine, and sawtooth (triangle) waveforms. They look like their names imply on an oscilloscope. They have no special significance other than they are descriptive of the type of AC wave they describe. It is like asking what are the different colors and what are their significance?

Do a web search for the parameters.  We would need much more information from you on sample types, volumes, etc and you capabilities, instrumentation available, etc.  All of these are factors in deciding a method.

www.ecglibrary.com hass all kinds of information\n\n-or try searching for ECG or EKG interpretation with any internet search engine, there is a plethora of resources out there\n\n-or go to a library (especially if you have access to a univeristy or medical school library) and find any of a thousand books on the subject

It doesn't give me room to list them all and explain them on here so let me direct you to a website I found that does a pretty good job:\nhttp://vergil.chemistry.gatech.edu/notes/quantrev/node20.html

What's to know?\n\nIt's the typical offset voltage, or DC component of the output.  The signal is AC.

Transverse electromagnetic waves (light,microwaves etc), the cosinewave shape is the same as calling something sinusoidal.\n\nSoundwave amplitudes can be sinusoidal.\n\nThe swing of a pendulum, simple harmonic motion.\n\nsinusoidal functions are solutions to many differential equations we find in nature.\n\nwaves on strings!

It sets an upper limit to the frequency spectrum that can be controlled (Nyquist aliasing effect)\n\nIt affects the computational burden of the controller\n\nIt affects the hardware performance requirements of the sampling system\n\nThere are tradeoffs that can be made between data acquisition accuracy and sampling rate, using digital filtering techniques

This again is a very vague question, I can only guess that the output stage shows the timing graphs. But unless you provide us with a link to a particular site or reference of what you are trying to ask, then we can not know the question exactly.\n\nPlease bear in mind you lose two points every time you ask a question. So make you answer as much as you ask !\n\nAnhar Hussain Miah

There are multiple units usable.  Try pascals, psi, torr, atm

I happen to care quite a bit about imaginary numbers as a person who studies electrical engineering.  In electrical engineering, we use the imaginary number (denoted i or j) to help represent sinusoidal waveforms, work with linear systems in the frequency domain, solve sinusoidally-excited RLC circuits etc.  It shows up quite a bit in my chosen area of study.  Even something as mundane as the voltage sine wave at a common household outlet can be represented by a phasor 120*e^(i*theta) where theta is the phase shift of the sinusoid.  Also, I hear physicists use imaginary numbers in some applications.\n\nAnyway, one of the interesting properties of the imaginary number is that when you square it you have -1 (since i = sqrt(-1)).\n\nSo:\ni^300 = (i^2)(i^2)(i^2)...(i^2)\ni^300 = (-1)(-1)(-1)...(-1)\n\nThe above set of (i^2) factors will repeat 150 times (the exponents add).  Since (-1)^150 = 1 we have our answer (check with your calculator or realize that an even amount of -1 factors will always give you 1).\n\ni^300 = 1

you would hear the resultant of the two frequencies both in frequencie and amplitude.
