Transistor Biasing The circuit shown in Figure is a typical biasing arrangement for a BJT-type transistor. The actual transistor for this problem can be modeled as 0.7-V battery in series with a 200-kΩ resistor.
Biasing allows signals that have both positive and negative variations to be properly amplified by the transistor. Select the two biasing resistors RA and RB so that 3 ± 0.1 V appears across RB.
The electrodes of a certain discharge tube have the form of a thin parallel-plate capacitor of plate separation d. The potential in the space between these electrodes has been found to have the form

If Nand gates are used throughoutand a ripple-carry design is used, calculate the delay through the adder, assuming all inputs are presented at the same instant, and counting D seconds per gate. Which output signal suers the worst delay.
A hydrogen sample is at equilibrium in a 1.5 Tesla magnetic field. A constant B1 field of 1.17x10-4 Tesla is applied along the +x'-axis for 50 microseconds. What is the direction of the net magnetization vector after the B1 field is turned off
Caffeine is a well-known beverage in both coffee and cola and has been shown to cause short-term increases in blood pressure. The article reported that drinking coffee doesn't seem to cause long-term high blood pressure. Can such a cause-and-effec..
