What are the two basic kinds of electronic signals?
The two basic kinds of electronic signals are analog signals and digital signals. Analog signals are continuous and can take on any value within a given range, while digital signals are discrete and represent information as a series of binary values (0s and 1s).
Why do you use binary digits to represent the presence or absence of electronic signals?
Since binary number digits only have 2 states (0 or 1) they are inherently useful to represent events which can be categorized into to states (signal present or absent, for example). A signal could come from a sensor which represents that something has happened (maybe it's part of an alarm system, and the sensor detects when a door is open or closed). Since it is a number, a microprocessor can be programmed to perform certain actions when this takes place.
What cause Electromagnetic interference?
Electromagnetic interference is caused by the presence of electromagnetic signals that disrupt the normal functioning of electronic devices. This interference can be produced by various sources such as power lines, radio frequency transmissions, electronic equipment, and lightning strikes. When these signals interfere with the operation of sensitive electronic systems, it can lead to malfunctions or data corruption.
Is a transistor a small electronic switch?
A transistor is used to switch electronic signals.
What are computers run by?
Electricity and Electronic signals.
What two factors affect the speed of nerve signals?
The diameter of the nerve fiber and the presence or absence of a myelin sheath are the two main factors that affect the speed of nerve signals. Larger diameter fibers and a myelin sheath help to increase the speed of nerve signal conduction.
Why is digital signal immune to noise?
Digital signals can gather information with noise because the information component is determined whether its presence or absence a data bit. Digital signals can processed by digital circuit components they are cheaper an easily to create in many components on a signal chip.
A device that conveys information with analog signals and digital signals is called?
An Electronic Device
What are the 2 types of electronic signals?
digital and analog
Why do you have to turn off your cellphones and electronic devices before flight take off?
I believe the signals from the electronic devices could interfere with cockpit and/or tower electronics/signals.
What are two forms of electrical signals?
Two forms of electrical signals are analog signals, which vary continuously over time, and digital signals, which represent data as discrete values. Analog signals can take on any value within a range, while digital signals have specific voltage levels to represent binary data.
Is fan is an electronic or electrical?
electrical. it does not amplify or modulate signals.
