Transformers make noise based on it out put if an transformer outputs is 400v maximum than a 398v be apply to that transformer it also make a noise because of that
Description : Define the term electrical noise. List types of noises.
Last Answer : Electrical Noise:- It can be defined as undesirable electrical signals, which distort or interfere with an original (or desired) signal. Types of noises:-
Description : Define the following terms : 1) Noise margin 2) Power fanout 3) Skew 4) Meta stability
Last Answer : 1) Noise Margin: It is a measure of noise immunity of a gate or circuit (noise immunity is the ability of a gate or circuit to tolerate any noise present in a signal without performing a wrong operation) ... OR A metastable state is half way between logic 0 and logic 1 .It is undefined state.
Description : Compare between BJT and FET on the basis of (i) Biolar/Unipolar (ii) Tharmal Runaway (iii) Noise (iv) Applications
Last Answer : Parameter BJT FET Bipolar/Unipolar It is bipolar device i.e. current in this device is carried by electrons and holes. It is unipolar device i.e. current ... in oscilloscopes, electronic voltmeters and other measuring and testing equipment because of their high input impedance.
Description : Switching of a lamp in house produces noise in the radio. This is because switching operation produces?
Last Answer : Switching of a lamp in house produces noise in the radio. This is because switching operation produces arcs across separating contacts.
