Q. Define Power-Supply Rejection Ratio?
An op amp's ability to disregard changes in power-supply voltage is measured by the power- supply rejection ratio (PSRR), which is specified by the change in offset voltage VOS for a 1-V change in dc power supply and is usually expressed in µV/V. A typical value is 15 µV/V.
Explain Acceptance cone? The fibre air - core interface is display below: In this figure Omax is the maximum angle, inside that the rays undergo total internal reflecti
why biasing of bjt transistor is essential?
NOR Gate NOR means NOT OR . it complements the output of an OR gate. The symbol of Nor gate in fig. (a) shows that a Nor gate comprises of an OR gate followed by a N
On which principle the generator works?
Operation - unijunction transistor: Operation : Imagine that the emitter supply voltage is turned biased and a small emitter reverse current flows. Then the intrinsic stand
What do you understand by DRAM and its refreshing? Dynamic RAM (DRAM) is fundamentally the same as SRAM, but this retains data for only 2 or 4 ms on an internal capacitor. But
What do you mean by internal data bus? Internal Data Bus: A bus which operates only in the internal circuitry of the CPU, communicating between the internal caches of memory
