At a frequency of 60 Hz, the core loss of a certain coil with an iron core is 1.8 W, and at a frequency of 120 Hz, it is 5.6 W. The peak flux density is the same for both cases. Determine the power loss due to hysteresis and that due to eddy currents for 60-Hz operation.
Second order unity gain Tschebyscheff low pass filter. The task is to design a second order unity gain. Tschebyscheff low pass filter with a corner frequency of fc = 12.5kHz and a 3dB passband ripple. Determine C1, C2, R1, and R2.
in the process of sampling an analog signal g(t) is multiplied by a periodic train of rectangular pulses c(t)each of unit area ,given that the pulse repetition frequency of this periodic train is fs and the duration of each rectangular pulse is T ..
Devise a system that will convert this temperature range into an 8-bit digital word with conversion from 00H to 01H at 200°C and from FEH to FFH at 350°C . An ADC is available with a 2.500-V internal reference.
Three 25.0KVA, 4801120VAC, single-phase, 60Hz transformers are connected delt-delta. The load on the bank is 50.0KVA, balanced load, with power factor of 1.0. A fault in one transformer required its removal, and the bank is operating open-delta. D..
An AM signal has a carrier frequency of 3 MHz and an amplitude of 5 V peak. It is modulated by a sine wave with a frequency of 500 Hz and a peak voltage of 2 V. Write the equation for this signal and calculate the modulation index.
Assume the coil around the toroid is one single coil and extends all the way around. A toroid is like a donut with a circular cross section. The following characteristics are given: Toroid material = sheet steel, N = 250 turns Inner Radius
To maintain a freezer box at -40°C on a summer day when the ambient temperature is 27°C, heat is removed at the rate of 1.25 kW. What is the maximum possible coefficient of performance of the freezer
What is the maximum no-load speed attainable by varying both VA and Radj ? What is the minimum no-load speed attainable by varying both VA and Radj ?
A sequential circuit hast two inputs (w1 and w2) and one output (z). Its function is to compare the input sequences on the two inputs. If w1 = w2 during any four consecutive clock cycles, the circuit produces a z=1
A pipe of inner radius 4 cm, outer radius 6 cm, and infinate length is centered on the z-axis. Charge is evenly distributed within the wall of the pipe in the amount of 16 coulombs per meter length.Find and Plot the electric feild density as a fun..
