2018 Fall EECS 314 HW problem 17 Sample solution by Alexander Ganago © 2018 Alexander Ganago Page 13 of 16 Last printed 11/16/18 2:02:00 PM File: 18c HW p17s.docx Part Four (15 points) Binary records of a pulse response Screenshot 2015-03-16-001.png File “514 Lab example.pptx” The oscilloscope, which you use in the lab, converts the analog input signals into the binary records at 8-bit resolution. It means that, in Analog-to-Digital conversion, the vertical axis of the screen is divided into 2^8 = 256 steps of the same size, which is equal to: ࠵?&}~− ࠵?&°±2²Here, ࠵?&}~corresponds to the very top, and ࠵?&°±– to the very bottom of the screen. Thus, as shown above, •The step at the very bottom of the screen has the binary number 0000 0000. •The step at the very top of the screen has the binary number 1111 1111. The screenshot above shows the input rectangular pulse and the output voltage of an RC circuit (measured across the capacitor). Three voltages are clearly marked: •V1 is the lowest voltage of both the input and of the output capacitor voltage •V2 is the highest output voltage (at the end of the pulse). •V3 is the highest voltage of the input rectangular pulse.
