What is the impedence of telephone line?
In the USA, should be 500 or 600 Ohms. It is 600 ohms as standard
What are the uses of complementary symmetry class B push-pull amplifier?
Sound amplification. Servo control systems.
chopper use a ststeing perpose.....
dc means direct current that is low voltage

What are the Features of stepper motor?
it is a mechanical device whereby signal will move a motor shaft degrees
What is Cam Actuated Drill Ahead Tool?
The CADA allows you to jet in surface pipe and drill out without making an additional trip out of the hole. The 36" relies on skin tension to stay in place, and after observation from the ROV the CADA will release the BHA and allow you to drill out the next section of casing while all returns are coming up through the pipe. Low fracture gradients in surface section don't allow returns on the backside of pipe.
What is the limitation of digital voltmeter?
The main limitation of a digital voltmeter is the resolution, analog voltmeters have a scale with divisions, and the user can read between these if the pointer does not fall on a specific division, digital voltmeters on the other hand are only able to display a finite number of values, although to be fair the resolution on lower ranges can be very small and is usually more than adequate. They also require batteries to work and from my experience, arent quite as well built as the good old AVO's how is it possible to view a meter when to read it you must directly position your eyes dead center and interpolate the thickness of a pointer. Lets not mention loading of an analog meter on the circuit itself. There are some draw back to digital meter like monotonic of the LSB but on a 7 digit readout it is not demoralizing I can read 1 mv on digital meter on an analog meter is mission impossible old timer.
What are the requirements to be a scientist?
A: You have to have thinking brain as opposed to education. I have known many educated idiots in my time thank you

Why are wind turbines not placed next to one another?
The wind farmers usually want to spread them out so the propellers do not collide. They also want to spread the turbines out so that they can catch the wind wherever it is.
a 2 bit counter is a counter which have only 2 bits i.e. the posibble counting states are 00, 01, 10,11,00. It may also be known as MOD 3 counter. It can be realized by using 2 Flip flop.
What are the types in waveguides?
3 types:
1.electromagentic waveguides
2.optical waveguides
3.acoustic waveguides
well yes and no yes it Will represents letter but as a function of an ASCII code like digital 41 Will represents the letter A
How do you amplify a square signal?
To easily do that all you need is a higher voltage level or the level that you desire . square waves usually are states of [1] or rail voltage and on[0] saturation voltage. to linearly amplify these square waves you will need a hi band pass amplifier . Possibly 50megahz or so
What are the Difference between dc motor and dc generator?
a motor Will do work by consuming power a generator is just the opposite
well if you doubled the coils it would be pie times the amount of voltage in the current squared
