What is Double Precision System? For any computer, the word length is fixed. Most present day computers are 16 bit and in a 16 bit computer, that is, in a computer with 16-bit word length,…
What is Diode Transistor Logic (DTL) Circuit? Diode Transistor Logic (DTL) is also a saturated logic and uses diodes, resistors and transisÂtors. The circuit diagram is shown in Fig. 47.2. The baÂsic DTL logic circuit…
What is Diode Resistance? What is Diode Resistance? - As already discussed, a forward-biased diode conducts easily whereas a reverse-biased diode restrains the flow of current, so a diode has a low forward resistance as…
What is Digital System?: Fundamental Properties of 1-D Digital System : A digital system can be defined as an operator which transforms an input sequence { x(n)} to an output sequence {y(n)} A system of…
What is Digital Storage Oscilloscope (DSO)?: Digital Storage Oscilloscope are available in processing and non-processing types. Processing types include built in computing power, which takes advantage of the fact that all data is already in…
What is DIAC? - Symbol, Construction, Operation and Applications A diac is an important member of the thyristor family and is usually employed for triggering triacs. A diac is a two electrode bidirectional avalanche diode…
What is Demodulation or Detection? - Need of demodulation: Demodulation or detection is a process of recovering the original modulating signal (intelligence) from the modulated carrier wave i.e., the demodulation is a process reverse of…
What is Current Mirror? - Circuit Diagram and its Workings The two-transistor current source, also called a current mirror, is the basic building block in the design of integrated circuit current sources. Figure 20.25 (a)…
What is Current Limiting Protection? The circuit arrangement for IC 723 as low voltage or high voltage regulator has no protection. If short circuiting takes place (when load demands more current), regulator IC makes efforts…
What is Current Foldback? The current limiting technique maintains a constant load current at some specified value and under overload condition, the Vout drops to zero. But, in case of short circuiting under overload conditions…
