What is an analog signal and a digital signal?
An analog signal is one which is continuous in time as well as continuous in amplitude . Example : sine wave, cosine wave. An Digital signal is one which is continuous in discrete in time. Example : square waves.
Which transmission is analog?
One with a continuous signal wave.
Is sine wave used in analog or digital?
No and yes. Digital signals are usually square or pulse waves. By Fourier analysis, however, every periodic wave, even a square wave, is the summation of some series (often infinite) of sine waves.
What sensor produces a square wave signal?
analog sensor
Which signal has a wider bandwidth a sine wave with a frequency of 100 hz or a sine wave with a frequency of 200 hz?
The signal that changes at a higher rate occupies greater bandwidth.
Is sine wave analog wave?
A: ANALOGUE IT can be AC or DC it is up to the application involved An analog signal can be a sine wave, a square wave a sawtooth wave or any other varying waveform
Drawing the waveform of analog signal?
Should be a sine ( or cosine) wave.
Why you are considering sine wave as ac but not cosine wave?
Sine wave is considered as the AC signal because it starts at 0 amplitude and it captures the alternating nature of the signal. Cosine wave is just a phase shift of the sine wave and represents the same signal. So, either sine or cosine wave can be used to represent AC signals. However, sine wave is more conventionally used.
What is an analog signal and a digital signal?
An analog signal is one which is continuous in time as well as continuous in amplitude . Example : sine wave, cosine wave. An Digital signal is one which is continuous in discrete in time. Example : square waves.
Is sawtooth signal analog?
Yes. A signal of plateaus shows quantized or discrete levels of one or the other voltage; only 2 states. A sawtooth signal has a spectrum of states and has many more than 2 discrete states and is thereby analog. A sine wave is also an example of an analog signal - a spectrum of intensity.
How can you use sine wave in a sentence?
The sine wave, with its repeating pattern, can represent a single frequency with no harmonics.
Which is more reasonable using a sine wave or square wave signal to determine slew rate?
It is more reasonable to use square wave rather than sine wave signal to determine slew rate. Both signal sources serve as a functional generator with the sine wave providing high purity waves.Ê
Which transmission is analog?
One with a continuous signal wave.
Is pulse wave an analog or digital signal?
Yes, it is
What is the difference if any between the demodulator part of a modem and coder part of a codec?
A coder can accept any kind of analog signal while demodulator can only accept a modulated sine wave. Then they generate the digital signal.

Why harmonics present in a signal?
if a signal is not a pure sine wave it must contain harmonics
