A square wave is a sum of an infinite number of sine waves (analogue). These sine waves consist of one wave called a FUNDAMENTAL, and all of the other waves are called HARMONICS. The fundamental is the same amplitude and frequency as the square wave. The harmonics are all odd, i.e. mathematically, the first harmonic (which is called the 3rd harmonic) is 1/3 the amplitude and 3 times the frequency of the fundamental. The next harmonic (called the 5th harmonic) is 1/5 the amplitude and 5 times the frequency of the fundamental. And so it goes with the next harmonic (the 7th), followed by the 9th and so on ad infinitum.
analog
Analog signals are transmitted as electrical waves.
Naturally occurring sound waves are analog, although they can be digitized.
When you convert digital signal to analog, it is called as an analog signal. The device used is called digital to analog converter.
Analog signals are transmitted as electrical waves.
An analog cellular system transmitted a caller's voice by converting the sound waves into a wave pattern
Digital = coputerized bits (ones & zeros). Analog = waves produced by certain hardware (generally speaking).
true
some smart person thought that a sqare should be called a sqare and how it got its shape well i think it was born like that
no light is a wave Analog are waves Digital is pulses (1 or 0)
2d = square 3d = cube 4d = tesseract ...
