ME 104 Lab #7 Quiz Name: Fall 2002 CIRCLE THE CORRECT RESPONSE TO EACH QUESTION.   1) According to Transistor-Transistor Logic (TTL),       which of the following voltages would      not       be considered either “logic low” or “logic high”? A. 0 V. B. 0.1 V. C. 2 V. D. 5 V. 2) T    he      Slotted Disc      on the DC Motor module can be used to obtain       A. one low pulse per 360 degrees of shaft rotation. B. one high pulse per 360 degrees of shaft rotation. C. 4 low pulses per 360 degrees of shaft rotation. D. 16 high pulses per 40 degrees of shaft rotation. 3) While driving the DC motor using pulse width modulation (P.W.M.),          pulse duration      (pulse       width) of 1.50 milliseconds will make the DC motor         A. rotate clockwise at a rate of 1 rotation per 1.50 milliseconds. B. rotate counter-clockwise at a rate of 1 rotation per 1.50 milliseconds.
