Consider the magnetic circuit of Figure with an air gap, while neglecting leakage flux. Correct for fringing by adding the length of the air gap lg = 0.1 mm to each of the other two dimensions of the core cross section AC = 2.5cm × 2.5cm. The mean length of the magnetic path in the core lC is given to be 10 cm. The core is made of 0.15- mm-thick laminations of M-19 material whose magnetization characteristic is given in Figure. Assume the stacking factor to be 0.9. Determine the current in the exciting winding, which has 100 turns and produces a core flux of 0.625 mWb.
A 10-kHz tone is used to frequency modulate a carrier; the peak deviation is 75 kHz. Use Carson''s rule to estimate the bandwidth.
Q. A 75-kVA transformer has an iron loss of 1 kW and a full-load copper loss of 1 kW. If the transformer operates on the following load cycle, determine the all-day efficiency:
The original 8086, which only had 1 MB of memory. This megabyte is dividing into low memory for IRQ tables, application memory and high memory.
What are the signals involved in memory bank selection in 8086 microprocessor? The 8086 based system will have two sets of memory IC's. One set for even bank and another for od
Q. Show an arrangement for multiplexing 64-to-1 by using four 16-to-1 multiplexers and one 4-to-1 multiplexer.
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
How is segmentation implemented in typical microprocessors? The first advantage is as memory segmentation has is that only 16 bit registers are needed both to store segment bas
