Question

how to convert j notation to phasors and vice versa?

Answer 1

just imagine a grid and the y axis is ur imaginary number while ur x axis is the real part. Graph out ur line using ur x and y values and use simple trig to figure out the angle and length of the line "

IE: 5+4j

line goes from (0,0) to (5,4)

Work backwards if u want to do the opposite.

Answer 3

I'm not sure what you mean by 'phasors' (unless your a Trekkie junkie )

I'm guessing that you mean a vector in polar coordinate notation (r,Θ). If that's the case, then to convert a vector from a complex number (a + jb) use

r = √(a² + b²)
Θ = arctan(b/a)

Remember that if a is negative, you have to add 180° (or π radians) to the answer your calculator gives you for arctan.

To go from polar to rectangular notation, use

a = r*cos(Φ)
b = r*sin(Φ)

and get

a + j*b

Answer 4

The formula for converting farenheit to celsius is c=5/9*(f-32). The formula for converting celsius to farenheit is f=c*(9/5)+32

Answer 5

Mark G is correct
Mail me at [e-mail] and Í'send you some VB5 code (similar to C) to do all the transforms for you, in any direction.

Answer 6

yes, all it is, as long as you stick to LTI (linear time-invariant) systems with no harmonic content.

It's just like switching form x,y (z) format to polar (cylindrical) format.

Answer 7

complex numbers rectangular to polar conversion,

a+jb .................. r/O

r= root a^2+b^2
O=(angle) Tan-1 b/a

other way

a=r cos O
b=r sin O
