that should be detected by the system o Meaning, the minimum time between any two events on an input signal. The time between the input event and the triggered output event is called latency . To reduce latency, a designer can reduce the synchSM period, and also minimize the state sequence between detecting the input event and generating the output event. In contrast, another section suggested minimizing microcontroller utilization by increasing the synchSM period. Thus, the designer must make a tradeoff , which is a balance between competing design goals, between minimizing latency and minimizing microcontroller utilization. The values sensors provide to a microcontroller commonly must be adjusted to reduce the impact of imperfections. This adjustment is known as input conditioning . Button debouncing is the task of ignoring the bouncing on the signal from a button so that a single press is interpreted by the system correctly as a single press and not as multiple presses. o Simple solution is to sample at a lower rate Filtering involves ignoring certain input events, such as electromagnetic interference ( EMI ). EMI can cause sensors or wires to output unintentional 1’s or 0’s for very brief periods of time, known as spurious signals, spikes, or glitches .

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
