A sine wave centered at zero will have a positive peak that is the same magnitude as the negative peak. This can be offset so the negative peak magnitude does not match the positive peak magnitude. For example a 1volt peak - neutral sine wave could be DC offset by 1 volt so the positive peak is at 2 volts and the negative peak is at 0.

Types of generators?
By the operation supply 1.AC generator 2.DC generator In DC generator we are having the following types according to the construction 1.DC Series Generator 2.DC shunt Generator 3.DC Compound Generator
What do you mean by DC generator?
DC generator is used to produce direct current. The basic DC generator have four basic parts 1. A magnetic field 2. A single conductor or loop 3. A commutator 4. Brushes
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 a compound dc generator?
generators are machines that convert machanical energy to electrical energy and could be AC or DC. if in a DC generator has it field armature connection in both series and parallel its said to be compound dc generator.
Can DC series generator start on no load?
yes.it is possible to start dc series generator on no load condition
4 what is the name of the circuit that adds a positive or negative dc voltage to an input sine wave?
This DC voltage is called the DC offset. Any decent signal generator will be able to add DC offset to the signal it generates. If you don't have one, simply connect a DC voltage to your signal.
How to removed a dc offset from the output of a frequency generator connected to a test circuit?
Run the test signal through a small isolation transformer.
Why signal generator is not used in half wave rectifier?
one is AC the other is DC
Different types of DC generator?
There are two types me dc generator 1 separately excited dc generator 2 self excited dc generator
What is the difference between audio generator and signal generator?
Audio generator will produce some range of frequency and level of a test signal meant for audio. A signal generator will produce a test signal but is a more general classification. For example a audio generator is a signal generator. When you know what type of signal you are looking for, then a signal generator will be called that type of signal. all depends on what you are testing. examples: video -> video signal generator audio -> audio signal generator
What is AC plus DC?
An offset AC wave. It will be offset by the magnitude of the DC applied.
Which is usually produced by a generator ac or DC?
An ac generator produces ac, a dc generator produces dc, it all depends on the generator.
What is AC offset?
Non-zero initial condition is called DC offset. DC offset is bad, and needs to be removed by HP filter as they cause distortion, non-linearity. If the mean/average amplitude of the wave is zero it has no DC-offset.
What was the first DC generator name and inventor why it is call generator?
first dc generator is max generator donno who invented t
How do you make DC generator?
A DC generator is a DC machine that is driven by an external rotating force. It is constructed the same as a DC motor.
Types of generators?
By the operation supply 1.AC generator 2.DC generator In DC generator we are having the following types according to the construction 1.DC Series Generator 2.DC shunt Generator 3.DC Compound Generator
What is an excitation signal?
It is a DC voltage that is applied to the generator's revolving field windings. This produces a magnet field that cuts the generators main coil windings, inducing an electrical current within the main generator windings.
