How noise occur in positive terminal?
noise do not occurs in positive terminals noise like all signals must have a return to be seen as evidence
What is the role of each component in the circuit?
Resistors limit currents in a circuit to a precise degree and control voltages within the circuit.Capacitors can store electrical charge and if coupled to a resistor giving timing functions. Capacitors block dc currents and act as coupling devices for ac signals.Transistors act as gain blocks that can amplify signals and actively respond to changing circuit conditions.Inductors or coils can act as frequency filters,generators or energy storage devices. Two coils wound on a common core are called transformers. These can step up and down voltages and isolate sections of a circuit from other parts.Diodes can rectify ac signals and block dc current as required.Integrated circuits contain all the above components in miniature
What is the meaning of Passive in Electrical?
Passive electronic components are those which do not amplify voltages or currents by themselves. These include resistors, capacitors and coils. Transistors and integrated circuits are known as' Active' components since they can amplify signals applied to them. In AC circuits coils (chokes) and capacitors DO change their characteristics when varying frequencies are applied to them but they are generally not classified as active components.
Why FDM is for analog signals and TDM is for digital signals?
FDM stnds for frequency division multiplexing and it is used only in case of analog signals because analog signals are continuous in nature and the signal have frequency. TDM-stands for time division multiplexing and it is used only in case of digital signals because digital signals are discrete in nature and are in the form of 0 and 1s. and are time dependent.
A device that conveys information with analog signals and digital signals is called?
An Electronic Device
What happens if you split one positive signal into two positive signals?
You end up with 2 positive signals. No difference.
How do you sum 3 dc signals to get 1 output?
add the signal voltages by connecting them in series - to +
What are the two types of signals of a computer?
There are dozens of types of signals but two major categories are digital and analogue.Digital signals have descrete voltage levels (if they are binary they represent on and off and may be 3.3V or 0 volts) while analogue signals have continuously varying voltages.
Why coupling capacitor is used inelectronics circuits?
To Block DC voltages and couple AC signals through to the next circuit.
What do the telegraph and Twitter have in common?
The both use a binary coding system composed of off and on signals.
How physics applied to home?
Gravity- shelves, walls etc. newtons laws Signals - voltages, currents from light, TV, computer, speakers etc.
A type of tissue that sends electrical signals through the body?
Nervous tissue is composed of neurons that use electrical signals to transfer impulses throughout the body.
Where is the positive signal in build a bear ville?
the positive signals are coming from the skate park square near the stripped chair and the beach ball
How noise occur in positive terminal?
noise do not occurs in positive terminals noise like all signals must have a return to be seen as evidence
What is the Relation of causal signals with causal systems?
Causal signals are signals that are zero for all negative time, while anitcausal are signals that are zero for all positive time. Noncausal signals are signals that have nonzero values in both positive and negative time.A causal system (also known as a physical or nonanticipative system) is a system where the output depends on past and current inputs but not future inputs i.e. the output only depends on the input for values of .REF BY: http://cnx.org/content/m11495/latest/http://en.wikipedia.org/wiki/Causal_system

Will my tv work in the Philippines?
Yes, as long as you have an HD signal. Digital signals don't change depending on where you go like some analog signals do because digital signals are only composed of 5 volts and 0 volts, 1's and 0's.
