1. In what power-supply application might I prefer to use an LC-type filter instead of the RC-type? Why?
2. What is the relationship between a half-wave rectifier and a full-wave rectifier?
3. Under what circumstances is it appropriate to use a voltage multiplier as part of a power supply?
4. List the advantages and disadvantages of the RC filter and LC filter.
ON a three-state bus, ten FCT three-state buffers are driving ten FCT inputs and a 4.7kΩ pull-up resistor to 5V. Assuming that no other devices are driving the bus, estimate how long the bus signal remains at a valid logic level
A baseband signal has frequencies from near dc to 4 kHz. Assume that the sampling rate is to be set at a value that will provide a guard band of 5 kHz for recovery. Determine the sampling rate (in kHz).

A sled is traveling at 4 m/s along a horizontal stretch of snow. The coefficient of kinetic friction is 0.05 . How far does the sled go before stopping ?
At a substation the primary of a step-down transformer (turns ratio = 1:26) receives the voltage from the high-voltage transmission line. Because of your usage, a current of 48.0 mA exists in the primary of this transformer.
What value would a weighted k-NN prediction model-with k = 16 (i.e., the full dataset) and using a weighting scheme of the reciprocal of the squared Euclidean distance between the neighbor and the query-return for the CPI of Russia when it is appl..
