What is CNR slot in motherboard?
Communications and networking riser (CNR) is a slot found on certain PC motherboards and used for specialized networking, audio, and telephony equipment. A motherboard manufacturer can choose to provide audio, networking, or modem functionality in any combination on a CNR card.
What is the function of CNR riser?
CNR is a scalable motherboard riser card and interface that supports audio, modem and network interfaces of core logic chipsets. CNR has the capability to minimize electrical noise interference by physically separating the noise-sensitive elements from the motherboard’s communication system.
What does a PCI slot do?
A PCI slot is a built-in slot on a device that allows for the attachment of various hardware components such as network cards, modems, sound cards, disk controllers and other peripherals. It was often a component of traditional do-it-yourself (DIY) desktop computer design.

What is AMR computer?
AMR (Audio/Modem Riser) is a specification developed by Intel for packaging the analog I/O audio functions of modem circuitry together with a codec chip (which converts back and forth from analog to digital) on a small board that plugs directly into a computer’s motherboard .
What are expansion slots in a computer case?

How is CNR calculated?
Contrast-to-noise ratio (CNR) is just the ratio of the estimated contrast and noise: CNR = C/N.
