Which acronym applies to serial data in which the "ones" and "zeros" are defined not only by the voltage value but also by the bit length (a "one" can be a short high-voltage pulse or a long low-voltage pulse and a "zero" can be a short low-voltage pulse or a long high-voltage pulse)?
A) IFR
B) CRC
C) VPW
D) PWM

Quizplus · Accepted Answer

DC) VPW (Variable Pulse Width) and D) PWM (Pulse Width Modulation) both involve defining data through the variation in pulse width. VPW is specifically used in automotive applications to encode data, while PWM is a broader technique used in various applications to control power or represent data by varying the width of pulses.
