What should be the phase margin and gain margin For stability?
A very high gain margin or phase margin produces stable feedback systems, however they may be sluggish in operation. If the gain margin is close to unity of the phase margin is close to zero, the system will be highly oscillatory and produce overshoots with large amplitudes that take a while to settle. Having a gain of 6 dB or phase margin of 30 - 35 degrees will give you a relatively stable system. However there exists cases where this may not be so. :-)
How do you calculate RC phase shift oscillators gain?
29
How do you calculate the number of turns that are required for the coils of three phase AC motor?
There is software that can be downloaded to help calculate the number of turns for a three phase motor. There are also diagrams which can be found for the most frequently used calculations.
How do you calculate 3 phase earth fault loop?
You can't have a three phase earth fault, you can have a phase to phase or a phase to earth fault. If you want the potential phase to earth fault current it will be your voltage times your impedance. If you want the phase to phase potential fault current then you should just double the above result.
How can you calculate the noise margin of various logic families?
A: There is no calculation involved it is specified by the manufacture as a level +/- volts or even current

(selling price - direct cost)/selling price = direct margin
How do you Calculate Net Profit Margin?
Net profit margin is calculated as net income divided by sales.
How do you calculate gross margin ratio?
gross margin ratio is calculated as >GROSS PROFIT/NET SALES
How do you calculate contribution margin rate?
Formula for contribution margin ratio = Sales – Variable cost / Sales
How do you calculate break-even?
Formula to calculate breakeven point is as follows: Break even point = Fixed cost / contribution margin Contribution margin = Sales - Variable cost
