What is the difference between characteristic table and excitation table in a flipflop?

A characterisitic table has the control input (i.e., D or T) as the first column, the current state as the middle column, and the next state as the last column. Basically, it tells you how the control bit affects the current state to produce the next state.
An excitation table has the current state as the first column, the next state as the second column, and the control bit as the third column. Basically, think of this as the state you have (first column), the state you want (second column), and what you must set the control bit (third column) to get the desired state you want. The excitation table is used to implement an FSM.

What is the difference between multidimensional and dimensional scaling?
The difference between multidimensional and dimensional scaling is in terms of relationship between physical characteristic and dimension. In the case of multidimensional scaling, each dimension can be connected to 2 or more physical characteristics, unlike dimensional scaling..
Difference between positive edge trigger and negative edge trigger for flipflop?
A: it does not apply to only flip-flop but to all kinds of logic circuits where a [+] transition from a less negative to a more positive level occurs [-] and the other way around meaning a +/- transition must occurs to transfer states.
What is an flip flop?
They are sandals that have a piece of plastic or cloth that goes between your toes. They are also called, though not by me, foot thongs, for that very same in between the toes thing. In New Zealand they are called Jandals ( short for Japanese sandals).
Why does the no-load characteristic differ for increasing and decreasing excitation current?
No-load characteristic knows as magnetic characteristic or open circuit Characteristic (O.C.C). It shows the relation between the no-load generated e.m.f in armature, E and the field or exciting current Im at a given fixed speed. The excitation voltage is directly proportional with excitation current. When excitation voltages increase so do excitation currents also increase.

Difference between truth table and excitation table?
truth table contains inputs and excitation table takes outputs as inputs
Difference between excitation table and truth table?
truth table gives relation between i/p & o/p. excitation table is use for design of ff & counters.

What is the difference between generator over excitation versus under excitation when attached to the grid?
Over Excitation is a condition when the Excitation System is providing too much field current and as a result, the rotor of the generator will over heat. The Excitation System is equipped with an Over Excitation Limiter. This limiter acts to reduce the Excitation Current if this condition exists Underexcitation is a condition when the generator is not getting enough Excitation Current. If the generator does not get enough Excitation Current, it can be un-synchronized with the grid. We call this slipping a pole. If this occurs, the generator can be severely damaged.

Difference between static excitation system?
It is called static excitation when you make use of solid state components like diode and thyristors to convert to pure dc and to use this dc for field excitation of synchronous generators. The field winding of synchronous generators can be excited by dc source only. It is called brushless excitation because use of carbon brushes are not made here.It is called dynamic excitation is when you make use of rotating brushes. Excitation is necessary to produce reactive power and also to regulate the voltage of synchronous generators.
What is the difference between a seperately excited DC generator and DC shunt generator?
The difference between a separately excited DC generator and a Shunt DC generator is that for a separately excited Dc generator , the excitation field winding is supplied by an external source different from that supplying the armature while for shunt generator, the excitation field windind is connected in series with the armature and supplied by a single source.
What is the difference between worm and Cd-rom?
The difference between CD ROM and WORM is that WORM allows to write once for the first time. Capacity is also a characteristic difference.
