Explain the Advantage of Synchronous Counters?
The most significant advantage of synchronous counters is that there is no cumulative time delay because all flip-flops are triggered in parallel. Therefore, the maximum operating frequency for this counter will be significantly higher than for the corresponding ripple counter.
Q. A transmission line with air dielectric is 25 m long. Find, in wavelengths, how long the line is at frequencies of 1 kHz, 10 MHz, and 100 MHz.
Solve using data from the DC machine data sheet, using the "hot" resistance value for all calculations. Note that the value of K on the sheet is for rated (100%) field flux. Assum
Question: (a) The forward path transfer function of a unity feedback control system is given by: (i) Draw the labelled block diagram representation of the control system.
Q. Explain the working principle of a d.c. generator. Explain clearly the function of commutator in d.c. machines. Sol. Working principle of a D.C. generator: For the 2- po
Q. Using K maps, simplify the following Boolean expressions: (a) F = A · ¯ B + A · B (b) F = A · C + C · D + B · C · D (c) F = A·B · ¯ C +B ·C +A·B ·D +B ·C ·D
Turn off Time The time interval between the instant when the SCR current has decreased to zero after external switching of the SCR voltage circuit and the inst
Currents induced in armature conductors of a d.c. generator are alternating. To make their flow unidirectional in the external circuit, we need a commutator. Moreover, these curren
You are given a binary image consisting of only zeros and ones, see image-A. Apply required morphological operations and give the output images on the grid.
Q. A three-phase, 600-kVA, 2300:230-V,Y-Y trans-former bank has an iron loss of 4400Wand a full-load copper loss of 7600 W. Find the efficiency of the transformer for 70%full load
