A simple on-off witch gives a digital signal. And the temperature / time sensor in my toaster.
But most sensors and transducers actually produce an analog signal, which is then digitally conditioned.
This conditioning is done because modern techniques allow quite large resolution (256 - bit resolution or better for example) to be developed.
And one notable advantage of digital signal processing is that signal noise is largely eliminated.

How did the modem get its name?
To send digital across an analog wire the signal is first laid on top of an analog signal. The process is called "modulation". It's the same thing that's done with television and radio, it's just a different type of signal.The modulated signal is sent across the wire and the MODEM at the other end receives the signal and decodes it.The process is called, "MOdulate, DEModulate, or more simply, MODEM.
What type of signal does ISDN use?
Out-of-band
What is the transfer of digital or analog data using digital or analog signals?
The transfer of digital or analog data using digital or analog signals refers to the process of transmitting information from one device to another, either through digital signals or analog signals. Digital signals are electronic signals that represent binary data, while analog signals are continuous signals that represent continuous data. The method of transfer depends on the type of data being transmitted and the technology being used for the transfer. For example, digital data can be transferred using digital signals through a computer network, while analog data can be transferred using analog signals through a telephone line. Regardless of the method used, the goal of the transfer is to accurately transmit the information from one location to another.
A hub that functions as a repeater inhibits the effect of what type of signal degradation?
Attenuation
How do you working of Digital Ramp Type ADC With the block diagram?

What are iris sensors?
Interferometric Reflectance Imaging Sensors are a type of sensor that converts a biological response into an electrical signal.
What type of signal degrades the most over longer distances?
digital
Why you are using sampling theorem in communication systems?
sampling is a one type of process use for converting into analog signal to digital signal.
What is difference between digital image processing and digital signal processing?
Digital Image Processing is a type of Digital manipulation pertaining to pictures and video. "Photoshopping" a digital picture is an example of Digital Image Processing. Another example is what takes place in a digital camera when the image is captured on the image sensor and converted into a JPEG file to be saved on a memory card. Digital Signal Processing is a generic term for any manipulation of a Digitally encoded signal, such as Audio, Video, or Radio Signals. This also includes Digital Image Processing where there is a signal being sent from one part of a system to another, such as in a digital camera. There are Microprocessors that are specifically built to process digital signals known as "Digital Signal Processors" (or DSP's).
Digital pictures and sounds are clearer than what type of signal?
NSTC/PAL (analog) video.
A telephone signal is digitized to reduce noise what type of conversion does this represent?
Analog-to-digital conversion
How many radio stations now broadcast a digital radio signal?

What is the difference between audio generator and signal generator?
Audio generator will produce some range of frequency and level of a test signal meant for audio. A signal generator will produce a test signal but is a more general classification. For example a audio generator is a signal generator. When you know what type of signal you are looking for, then a signal generator will be called that type of signal. all depends on what you are testing. examples: video -> video signal generator audio -> audio signal generator
What type of output does a S-PDIF port provide?
A 2-channel digital audio signal, or a encoded DTS or Dolby Digital surround sound audio stream.
What type of signal does a potentiometer produce?
A: Potentiometer does not produce any signal it is merely a variable resistor whereby any signal impressed on it can be variably taken out of the wiper as a linear function or logarithms function depending on the requirement of the design
What type of signal uses existing telephone copper wires to send and receive?
both analog and digital.
Does a repeater reduce the effects of attenuation for a digital transmission signal?
It depends on the repeater. Those that receive a signal, buffer it in real time and pass it on as a digital signal will reduce the effects of attenuation. Those that receive a signal and regenerate it with a new clock signal will generally eliminate the effects of attenuation completely.The type of repeater used depends on where and how it is used as well as the signal that is being transmitted.
