For a given zener diode circuit, find out the input voltage range
(a) If the primary coil, Nsubp has 500 turns and Vsub2=240V than, how many turns does the secondary coil have (b) If the turns ratio is 5, and Vsub2=240V, than, what is the current flowing through both coils
How can one determine whether a given signal is real-valued or complex valued from the Fourier series coefficients 1) A signal with a fundamental period of 12, and a5=1, a6=1 (rest are zeros)
Design a 7.5 V zener regulator using a 7.5 V zener diode specified at 11mA. The zener has rz= 20 ohms and a knee current of 0.5 mA . Design the appropriate value of the resistance r and calculate the output voltage variation when the supply voltag..
design must mention the values of the resistors, capacitors, average and maximum current through the diodes, transformer turn ratio and the current carrying capacities of the transformer coils. Present these values neatly in a tabular form.
A permanent magnet DC motor with a 10 ohms armature is stopped by dynamic braking. at operating speed, the counter EMF in the motor armature is 15 volts. What will be the peak current through the switch at the instant it shorts out the motor
The following signals are sampled using a train of impulses with periodicity kT: signal x(t) Is sampled to obtain and signal y(t) Is sampled to obtain yc(t) Determine the range of values for T that allows complete recovery of x(t) from xc(t)
A traffic light is installed at a junction of a railroad and aroad. The light is controlled by two switches in the rails placed 1mile apart on either side of the junction. A switch is turned onwhen the train is over it and is turned off otherwise.
A sin wave that is 1/2 wave rectified has the following properties: Vmax=14 Period=8mS Calculate Vrms?
Using energy concepts, find the internal self inductance per unitlength of a loss-less, conductive solid wire of radius ρ. You may assume that the current is uniformlydistributed through the cross-section of the wire.
A medium wave antenna mast is 50 m high and is operating at 1 MHz with a top loading the effective height is equal to 45 meters. with input power = 100 Kw , find the input current given that the ground resistance = 2.5 ohm .
Generate the Bode frequency response plots for your filter. Verify that your filter has the correct cutoff frequency - Find the pole locations and plot the pole locations in the s-plane.
1) Design inverting amplifier circuits with gains of 1, 10,and 100, and show the component values. 2)Calculate the inverting amp output at each gain setting for V2 is1.0Vpp at 100Hz
