What does an led do in an electronic circuit?
the function of an led is to give of light coming through an electrical circuit
What is slew rate?
slew rate is the ability of an amplifier to reproduce amplified version of the input signal in terms of frequency and phase. The input signal amplitude change is fast. But the amplifier will take some time to give response to the changes in input signal. i.e. how fast the amplifier tracks the input signal is the slew rate. For an amplifier the slew rate should be high in order to avoid signal distortion. The rate of change of the output voltage of an amplifier for the given input signal change is called the slew rate.
Which coupling gives the higher gain in case of amplifier?
DC coupling on the input/output will always give higher gain because AC coupling involves inserting a capacitor, which adds impedance and augments the signal. AC coupling is sometimes necessary though, for such purposes as eliminating DC offset on the base of a transistor, or eliminating a DC offset in a single supply opamp circuit.
How many 150 watt flood lights can be on a 20 amp circuit?
The voltage needs to be known to give an answer to this question.
How can you design a digital logic circuit for a traffic light system?
this depend on the way where you want to place your design you have to design a timing circuit first.(u can use IC 555 ) after that according to your variable and expression give this output of timing circuit to LOGIC gates serially after every one minute the output of timing circuit will change and gates are also change their position and indicate traffic light.
What class of amplifier conducts for 100 percent of a cycle?
Class A. Wikipedia has a really good set of data to give you a start on understanding amplifier classes.
Used as a form of safety device in a circuit give one word answer?
A fuse or circuit breaker will fit this description.
How op amp works as oscillator?
oscillator needs positive feedback in order to produce the undamped oscillations .This is done with help of he amplifier circuit.The oscillations are produced by the tank circuit cosisting of inductor and capacitor.The output of this tank circuit is fedback to the transistor which amplifies it and give back to the tank circuit input.If the gain of the circuit consisting of tank circuit and amplifier is more than one and the feedback given to tank circuit is in phase then we get undamped scillations as the output.
Can you amplify DC voltages?
Yes, certainly - an operational amplifier circuit (see e.g. Wikipedia) will do this. For instance, a non-inverting amplifier circuit with a gain of 10 will give 1.0V output for 100mV input, 2.0V for 200mV, and so on (limited by the supply voltage of the amplifier). Physical sensors such as thermocouples or strain gauges often need DC amplification to make their outputs easier to measure.
What is tuned amplifier Can Somebody give exact definition?
Narrow band amplifier
What is a Class AB power amplifier?
That would take some time to explain so I'll just give you a link. http://www.bcae1.com/ampclass.htm
What are the narrative job description and technical class specificationns for fire officers in the fire department?
Try using the O*Net it will give you a complete job description for a fire officer but it might not tell you the class specifications. Type O*Net in google for website.
Why are amplifiers needed in electronic circuits?
An electrical circuit is used to guide electricity through a path. This is used because when electricity is guided to various things it can power them.Anything that uses electricity.It's called a circuit because the electrons have to circulate back to where they came from.A battery has two poles. The circuit is only complete when both terminals are connected via the device(s) driven.A generator has two poles from the coil inside. Electricity can only flow when both ends of the coil are attached.
How do you increase bass output in a guitar amplifier by circuit modification?
Every amp is designed differently, so there's no one answer to give you. Your best bet is to use an EQ pedal to boost the bass level going into the amp.
What happens if a capacitor in an audio amplifier becomes open circuit and how does this affect the output?
Without knowing the location of the capacitor in the amplifier (which you do not give) no specific answer can be given, only possibilities assuming various locations (e.g. input coupling, power bypass, bias networks, interstage coupling, virtual grounding of shields). Each will have one or more characteristic symptoms it could produce in the output.
