  2. Carrier-to-noise ratio - Wikipedia

    en.wikipedia.org/wiki/Carrier-to-noise_ratio

    In telecommunications, the carrier-to-noise ratio, often written CNR or C/N, is the signal-to-noise ratio (SNR) of a modulated signal. The term is used to distinguish the CNR of the radio frequency passband signal from the SNR of an analog base band message signal after demodulation. For example, with FM radio, the strength of the 100 MHz ...

  3. Signal-to-interference ratio - Wikipedia

    en.wikipedia.org/wiki/Signal-to-interference_ratio

    The CIR resembles the carrier-to-noise ratio (CNR or C/N), which is the signal-to-noise ratio (SNR or S/N) of a modulated signal before demodulation. A distinction is that interfering radio transmitters contributing to I may be controlled by radio resource management , while N involves noise power from other sources, typically additive white ...

  4. Contrast-to-noise ratio - Wikipedia

    en.wikipedia.org/wiki/Contrast-to-noise_ratio

    Contrast-to-noise ratio (CNR) [1] is a measure used to determine image quality. CNR is similar to the metric signal-to-noise ratio (SNR), but subtracts a term before taking the ratio. This is important when there is a significant bias in an image, such as from haze. [ 2 ]

    The SNR values are given for the rectangular region on the forehead. The plots at the bottom show the signal intensity in the indicated row of the image (red: original signal, blue: with noise). Signal-to-noise ratio (SNR or S/N) is a measure used in science and engineering that compares the level of a desired signal to the level of background ...

  6. Eb/N0 - Wikipedia

    en.wikipedia.org/wiki/Eb/N0

    is closely related to the carrier-to-noise ratio (CNR or ), i.e. the signal-to-noise ratio (SNR) of the received signal, after the receiver filter but before detection:

  7. Signal-to-interference-plus-noise ratio - Wikipedia

    en.wikipedia.org/wiki/Signal-to-interference...

    In information theory and telecommunication engineering, the signal-to-interference-plus-noise ratio (SINR [1]) (also known as the signal-to-noise-plus-interference ratio (SNIR) [2]) is a quantity used to give theoretical upper bounds on channel capacity (or the rate of information transfer) in wireless communication systems such as networks.

    en.wikipedia.org/wiki/Police_Intelligence_Department

    The Police Intelligence Department (PID) is a staff department of the Singapore Police Force (SPF). Its primary purpose is to collate and analyse information obtained from the various departments of the SPF, as well as other sources, to support law enforcement activities in Singapore. The department is also the staff authority on matters ...

    A Singaporean police vehicle. In Singapore, law enforcement is principally led by the Singapore Police Force (SPF), and supported by other agencies including the Singapore Prison Service, Central Narcotics Bureau, Corrupt Practices Investigation Bureau, Internal Security Department, Immigration and Checkpoints Authority, and Singapore Customs ...
