Question 20 (1 point)
The ________ circuit overcomes the problem of false switchingcaused by noise on the input(s).
A) Schmitt trigger
B) input noise eliminator
C) differentiator
D) input buffer
Confused on this one, mainly the wording. Books states a Schimtttrigger is built in a comparator for hysteresis which helps withnoise, but a schimitt triiger is not a \"circuit\" from what I gatherin the text. Out of all the options there, the only one the bookrefers to as a \"circuit\" is a differentiator. But it states that isnoisy which the question reads from what I gather stops/overcomesthe noise.
The other two options are not noted anywhere in the chapter.
My reference material is from Electronic Devices by Floyd 10thEd Chapter 13. Any help will be appreciated. Thank you.
