Design a circuit for easy connection between a TTL gate and a TRIAC that uses a buffer transistor between the output port of the gate and the TRIAC.
(a) In the 1st and 4th quadrants, (b) In the 2nd and 3rd quadrants.
In addition, the distance between the components of the exciton is always such that there are intervening semiconductor atoms. Thus e in the Bohr formulation must also be replaced by Ks e0, where Ksis the semiconductor dielectric constant.
Problem Feeder - Transformer, A single-phase load is supplied through a 35 kV feeder whose impedance is 115 + j380 Ohms and a 35 kV, 2400 V transformer whose equivalent impedance is 0.26 + j1.21 Ohms referred to its low voltage side.
3-singlephase 2 winding transformers, each rated 500 MVA, 13.8/199.2 kV, with leakage reactance Xeq = 0.10 per unit, are connected to form a three-phase bank. Winding resistances and exciting current are neglected.
A Gaussian random process having a mean value of 2 and a variance of 4 is passed through an ideal half-wave rectifier. a) Let Xp (t) represent the random process at the output of the half-wave rectifier
A slotted line is used to measure the voltage maximums and voltage minimums on a transmission line with a characteristic impedance of 50 . The voltage maximum is measured as 7.5 V and the minimum is 5 V. The line is terminated with a purely resist..
A)what is the maximum Doppler for a vehicle speed of 160 km/hr at 900MHz. B)what is the minimum doppler(most negative for this case) C)for this range of Doppler what is the corresponding speed at 1800MHZ
The received power at a receiver antenna is -38 dBm. If the system impedance is 50 Ohms, what is the voltage at the receiver antenna. What is the total average power for a commercial AM transmitter with an unmodulated carrier power of 20 kW and 100%..
Determine the transfer function for a first-order high filter with a cutoff frequency of 1000 radians per second and passband gain of 1 using the following types: a. 3-dB Butterworth type. b. Chebyshev type with 1 dB ripples on the passband.
1.write down the electrical status equation for the circuit with serial connection of RLC- elements in vector form and darw diagram for this circuit. 2. Describe the work of electrical source in the voltage generator regime. and what is the working..
A square cross section, air filled toroid has Inner radius 12 cm. outer radius 14 cm. and thickness 2 cm. How many turns are required to produce an inductance of 1 mH
On a breadboards, hook up an IR LED to provide an infrared light source for signaling the phototransistor as shown in Figure 2 below. Use a pushbutton switch to turn the IR LED on and off.
a) Draw a sketch of the spectrum of x(t) = sin3(400πt) Label the frequencies and complex amplitudes of each component. Determine the minimum sampling rate that can be used to sample x(t) without aliasing for any its components.
