Determine if each statement is True or False: 1. Digital signals can have multiple continuous levels. 2. Analog temperature sensors produce a continuous range of voltages that can be read by Arduino. 3. A light switch is an example of a device that operates using digital signals. 4. Analog signals only have two states: on or off.
Understand the Problem
The question is asking to evaluate a set of statements regarding digital and analog signals and determine if they are True or False.
Answer
False, True, True, False
- False. Digital signals have discrete levels, not continuous. 2. True. Analog sensors output continuous voltages. 3. True. Light switches operate using digital signals with two states: on and off. 4. False. Analog signals have a continuous range of values.
Answer for screen readers
- False. Digital signals have discrete levels, not continuous. 2. True. Analog sensors output continuous voltages. 3. True. Light switches operate using digital signals with two states: on and off. 4. False. Analog signals have a continuous range of values.
More Information
Digital signals are characterized by discrete values, typically two states (e.g., binary 0 and 1), while analog signals can take a wide range of values. Devices like light switches function using digital signals.
Tips
A confusing point is that 'digital' is often associated with electronic devices, but it specifically refers to signals with discrete states. Be sure to differentiate between continuous and discrete when defining analog and digital.
