Buffer
A buffer is a logic circuit that amplifies the current or power. Basically it is used change the driving capability of a logical circuit. Therefore it is sometimes referred as drive. A simple buffer and tri state buffers (active high and active and low ) are shown in figure.
A tri state buffer if enabled provided the same logic level of the output as that of input i ,e if input is at logic 1 then it provides logic 1 output.
Explain the Tap Changing Transformers? This is the most popular form of voltage control at all voltage levels. It is based on changing the turns ratio of the transformer, hence
configured as attraction force rotation and brief stutter at zero degree putting a diode to a capacitor collecting energy of collapsing magnetic field to recycle on next power inpu
Q. In a depletion MOSFET for which V P = 3 V and I DSS = 11mA, the drain current is 3mA when v DS is set at the largest value that will maintain ohmic region operation. Find v G
Considering Figure, let balanced positive-sequence, three-phase voltages with ¯V AB = 100√3 0° V (rms) be applied to terminals A, B, and C. The three-phase wye-connected balanced
State the functions of a fuse. Fuse is a protective device that made of a thin wire or strip. This strip or wire is placed with the circuit this has to protect, therefore the
Q. Determine voltage and current gains for the CE BJT amplifier shown in Figure with the following parameters: R 1 = 30,000, R 2 = 9000 ,R C = 750 ,R E = 250 , R L = 1000
To do the basic laboratory experiments related to the electrical engineering course, students need to have some basic understanding about the measuring tools, apparatus, components
having looked at the circuit, i first wanted to start my frequency from 0 and plot for 10000 to 20000. so in matlab i used f = 0:10000:20000; but the equation for frequency is f= 1
Q. Draw the developed diagram of a simplex progressive 2 layer lap winding for a 4 pole generator with 12 coils clearly indicating the position of brushes. Sol. No. o
Q. The magnitude spectrum of a continuous image is as given below. a) Sketch the frequency response of the sampled spectrum if ωs =1.5 ωm along x and 3ωm along y directions
