ECET 105 Week 1 Homework Assignment # 1 Does a typical computer have any analog outputs? If so, what are they? List three advantages of digital signal representation as compared to their analog representation. Convert 126 x 10 2 to scientific and engineering notations. Make the following conversions: Convert 0.34 seconds to milliseconds. b. Express 0.0005 x 10-4 farads as picofarads. The frequency of a signal is equal to the reciprocal of the signal’s period (f = 1/p). For a computer with a 2....
