Document Summary

Sysc 4405: midterm exam (#:1) october 24, 2011. These weapons send a sequence of electrical pulses into the subject, and are designed to stimulate nerves and cause muscular incapacitation. We consider a cew which sends pulses of the shape below at a rate of 20 pulses/s. In order to validate the reliability of these devices, they are tested by ring into a dummy load (normally a 600 resistor) and the voltage signal measured and digitized. A recent standard recommends a sampling frequency of. Instead, in this exam, consider an inadequately sampled signal using fs = 50 ksample/s, used with a 6 bit a/d converter. The a/d converter"s input range is 1500v . The electrical output from the weapon is a series of pulses, x(t), described by the equation below and the graph at right. x(t) = 2000 u(t)u(100 s t)(1 t. 1000: (1 point) your exam is exam number 1.
