Verified Answer

The total current flow in an ECL circuit remains relatively constanta)...

ECL - Emitter Coupled Logic circuit uses differential pair of transistors biased by constant current source coupled to emitter.

Depending on the logic the current flows from one transistor or the other, the total current drawn by the circuit remains same regardless of logic.

Since the current is constant during switching , hence unlike in CMOS or TTL no noise spikes occur during switching.

Similar Defence Doubts

Read the following passage carefully and answer the questions given below it.Some gene mutations produce characteristics so undesirable that it is difficult to imagine any reasonable change in environmental conditions that would make them beneficial. There are mutations that lead to the nondevelopment of hands and feet, to the production of blood that will not clot, to serious malformations of essential organs, and so on. Any mutation that brings about death before the gene producing it can be passed on to another generation is a lethal mutation. A gene governing a lethal characteristic may be dominant. Under such conditions, the lethal gene is removed in the same generation in which it is formed. The lethal gene may, on the other hand, be recessive. Its effect is then not evident if the gene it is paired with is normal. The normal gene carries on for both. When this is the case, the lethal gene will remain in existence and will, every once in a while, make itself evident. These undesirable genes may be passed along for generations, even if dominant, before natural selection culls them out. The more seriously undesirable they are, the more quickly they are removed, but even outright lethal genes will be included among the chromosomes from generation to generation provided they are recessive. These deleterious genes make up the genetic load. The gene pool is necessary for the flexibility that will allow a species to survive and evolve over the eons and the genetic load is the price that must be paid for that. The size of a genetic load depends on two factors: The rate at which a deleterious gene is produced through mutation, and the rate at which it is removed by natural selection. When the rate of removal equals the rate of production, a condition of genetic equilibrium is reached and the level of occurrence of that gene then remains stable over the generations.Q.What is a lethal mutation?
