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: a. 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). The signal shown below is a sine wave as it might be d...
