The difference between square and square roots?
Algebraically if we have a number 'x^2' Then its square is (x^2)^2 = x^4 For the square root of x^2 = +/-x
What is the size difference in size between New Zealand and Belgium?
Belgium has a population of 10 500 000, and an area of 30 300 square km New Zealand has a population of 4 300 000 and an area of 268 600 square km
What is meant by parasitic capacitor?
Parasitic capacitance is the unwanted capacitance between: 1. A signal line and other signal line. 2. A signal line and earth. 3. A signal line and power supply line. Not that, I remember all (even most) of the effects, let me answer you with whatever I remember: 1. Unwanted coupling between two different signals, resulting in "crosstalk" between two signals. One signal interferes with other and other interferes with one. 2. attenuation / distortion of high frequency signals which have high impedance / limited current capability. 3. Ringing (unwanted oscillations) rising edge and falling edge of the signals rectangular / square wave.
What watch does mark benford wear in flash forward?
Looks like Armitron Men's Square Black Digital Sport Watch (408115BLK)
What is the difference between the Gobi Desert and the Atacama Desert?
The Patagonian Desert (260,000 square miles) is much larger than the Atacama Desert (54,000 square miles).
What is pwm?
PWM is Pulse Width Modulation. It is a Digital control is used to create a square wave, a signal switched between on and off.
What advantage do regenerative repeaters have when used for digital communication?
When any digital signal is transmitted over a pair of wires, it degrades in amplitude. Regenerative repeaters receives the incoming signal, extracts the clock, then regenerates the original signal as a clean digital square wave as if it was the original signal transmitted from the source. Thus the name repeater.
What is the difference between periodic and aperiodic signals?
A signal which repeats itself after a specific interval of time is called periodic signal. A signal which does not repeat itself after a specific interval of time is called aperiodic signal.A signals that repeats its pattern over a period is called periodic signal,A signal that does not repeats its pattern over a period is called aperiodic signal or non periodic.Both the Analog and Digital can be periodic or aperiodic. but in data communication periodic analog sigals and aperiodic digital signals are used.
What is an analog signal and a digital signal?
An analog signal is one which is continuous in time as well as continuous in amplitude . Example : sine wave, cosine wave. An Digital signal is one which is continuous in discrete in time. Example : square waves.
What is difference between centimeter square and square centimeter?
No mathematical difference.
What is the difference between Analog signal and Binary signal?
An analog signal has a sine wave form and a binary signal has a block "wave" form. The binary signal is either on or off ("up" or "down"), and never anything in between. analog: http://img99.imageshack.us/img99/7723sineuk6.jpg binary: http://img154.imageshack.us/img154/1894binarypb6.png
What's the difference between square kilometers and kilometers squared?
There is no difference between square meters and meters square. for simplicity we use these in different form.
What is the difference between a square pyramid and a pyramid?
the difference between them is that the bottom face is different one of them is a rectangle and one of them is a square
Why the frequency of a digital signal is infinite?
actually the frequency of a digital signal in infinite because assuming the signal is a square wave for each point in time eg 1 sec the amplitude can remain at max or "dc" for any number of bits assuming 1 bit = dc for 1 sec/clock cycle
What is the difference between a square pyramid and a rectangular pyramid?
the difference between them is that the bottom face is different one of them is a rectangle and one of them is a square
What is the difference between 7-8 Reggae and normal 7-8 time?
It is the same as the difference between a blue square and a square.
What is the difference between units square and square units?
There isn't a significant difference, just which ever you prefer.
