What is Gray code? (Definition, Conversions & Examples): This Gray code belongs to a class of codes called minimum-change code, in which only one bit in the code group changes when going from one step…
What is Frequency Response of an Amplifier? The voltage gain of an amplifier varies with signal frequency due to the effect of variations in circuit capacitive reactance with signal frequency on the output voltage. The…
What is Focusing Device in Cathode Ray Oscilloscope and why it is required? Because of the mutual repulsion between the electrons, the convergent beam coming out from the accelerating anode has a tendency to spread…
What is Flood Lighting? - Definition and Calculations Flood lighting means flooding of large surfaces with light from powerful projectors. It is employed to serve one or more of the following purposes. Aesthetic Flood lighting:…
What is Flash Memory in Digital Electronics? Flash Memory in Digital Electronics (sometimes called "flash RAM") is a type of constantly-powered nonvolatile memory that can be erased and reprogrammed in units of memory called Blocks.…
What is Extrinsic Semiconductor? Intrinsic (or pure) semiconductor by itself is of little significance as it has little current conduction capability at ordinary room temperature. However, the electrical conductivity of intrinsic semiconductor can be increased…
What is Excess-3 Code? (Definition and Examples) The excess-3 code, abbreviated as XS-3, is an important 4-bit code sometimes used with binary-coded decimal (BCD) numbers. It possesses advantages in certain arithmetic operations. The excess-3 code…
What is Emitter Coupled Logic (ECL) Circuit? Emitter coupled logic (ECL) is the fastest of all logic families and, therefore, is employed in applications where very high speed is essential. High speeds have become possible…
What is Electropolishing, Electrotyping, Electrofacing, Electrometallisation and Anodizing Closely allied to bright dipping is electropolishing, which utilises anodic treatment in specially formulated electrolytes to bring up a polished surface on such metals as stainless steel.…
What is Electroplating in Electrolysis and its Working Principle Electroplating is an art of depositing a superior or a more noble metal on an inferior or a base metal by means of electrolysis of an…
