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.
Pinch off Voltage: The current in N-JFET because of a small voltage V DS is described by: I DSS = (2a) W/L (qN d μ n V DS ) In which 2a = channel thickness
Q. Assuming the diode to obey I = IS (e V/0.026 -1), calculate the ratio V/I for an ideal diode with I S = 10 -13 A for the applied voltages of -2,-0.5, 0.3, 0.5, 0.7, 1.0, and

In order to demonstrate aliasing, make a plot of the signal x(t) = 3 cos 2π10t - cos 2π30t which approximates a square wave with W = 30 Hz. If the sample points are taken at
What is Voltage Multiplying DACs? Multiplying DACs function on the principle of producing a weighted sum analog signal where the sum is proportional to the digital input signal
Comparison of Analog-Modulation Systems The comparison of analog modulation systems (conventional AM, DSB SC, SSB SC, VSB, FM, and PM) can be based on three practical criteria:
Q. For the circuit of Figure: (a) Find an expression for the power absorbed by the load as a function of RL. (b) Plot the power dissipated by the load as a function of the lo
