An output pulse of 5μs duration is to be generated by a 74LS122 one-shot. Using a capacitor of 10,000 pF, determine the value of external resistance required.
A half-wave rectifier circuit with a 1-k ohm load operates from a 120-V (rms) 60-Hz household supply through a 10-to-1 step-down transformer. It uses a silicon diode that can be modeled to have a 0.7-V drop for any current.
A box contains balls that are identical except for color. Initially the box contains three blue and two green balls. A ball is drawn at random from the box and its color is observed. This first ball is then put back in the box, and then four balls..
how does your answer change if the bubble is elongated in the direction of the electric field and sphere and the dielectric shell are placed in an initially uniform electric field E 0 in the z direction.
For the given circuit, determine the function of it I.e. is it OR gate? Or AND gate,.. Show all your answer, also draw the symbol and truth table of it.
Suppose that data are stored on a 1.4-Mbyte floppy diskettes that weight 30 g each. Suppose that an airliner carries 10,000 kg of those floppies at a speed of 1000 km/h over a distance of 5000 km. What is the data transmission rate in bits per sec..
An isolated free electron is traveling through an electric field from some initial point where its coulombic potential energy per unit charge (voltage) is 17 kJ/C and velocity = 93 Mm/s to some final point where its coulombic potential per unit ch..
Design an amplifier circuit to amplify the small output voltage of a transducer of 50mV peak to deliver an output voltage of 8V peak to a 10k ohm load. (This design will produce 1 simulated circuit and an ac output and gain verified using an oscil..
A star-bus hybrid topology consists of a main three branch star toplogy with each branch connecting three stations in a bus topology. This toplogy is changed to a new bus-ring hybrid topology with main five station bus topology.
A first-order circuit, having a gain of 10 at dc and a gain of 1 at infinite frequency, has its pole at 20 kHz. Find its transfer function.
When a sinusoidal signal is used to frequency modulate a VHF carrier, the required bandwidth is 200 kHz. It is desired to retain the same modulation index while reducing the necessary bandwidth to 100 kHz.
When making an impedance diagram, does inductive reactance go on the positive Y-axis, or the negative Y-axis. How about capacitive reactance. How do these graphical representations relate to the phase angels of the reactances.
The DC resistance of the primary windings of a certain transformer is found to be 22ohm while the resistance of the secondary windings is 0.8ohm. When a 60 Hz sinusoidal source is connected to the primary "with the secondary open circuited"
