We are imaging a field for NASA from a satellite. The field has vertical (sinusoidal) stripes that repeat at a rate of 1 stripe per meter. Our satellite has a CCD sensor (camera) that is 1 cm x 1 cm. This sensor has 1000x1000 pixels. The image on the sensor is (14/ z) as wide and as tall as the actual image on the ground for a height of z meters. What is the highest elevation (z) that can be achieved by the satellite such that the image of the stripes is adequately sampled? Hint: the Nyquist rate applies.

A Y-connected load with an impedance of 12 - j15 per phase is connected to a balanced Delta-connected 208-V, 60-Hz, three-phase, positive phase-sequence supply. Determine (a) the line and phase voltages
A 400-V three-phase, wye-connected synchronous motor delivers 12 hp at the shaft and operates at 0.866 lagging power factor. The total iron, friction, and field copper losses are 1200 W.
The LM358 op amp can be a single or dual supply op-amp. This mean that it can operate with just a single supply i.e. + 5 volt or with dual supplies i.e. (+ and -) 5 volt supplies. With a inverting configuration with dual supplies (+5v and -5v) bei..
Design and sketch a band pass filter consisting of an RC high-pass filter with a cutoff frequency of 300 Hz and an RC low-pass filter with a cutoff frequency of 700 Hz. Carefully select the R and C of each filter so that one filter does not load t..
The bit energy to one-sided noise density at a PCM receiver input is 30 dB. Referring to the figure above, determine the approximate detected S/N ratio (in dB) for 8-bit BPSK with a matched filter detector.
