:
a lessening of the amount, force, or magnitude of something
specifically : a weakening of the connection between an illegal police procedure and the evidence obtained by it such that the evidence is admissible at trial as an exception to the exclusionary rule.
What do you mean by attenuation?
Attenuation is
the loss of signal strength in networking cables or connections
. This typically is measured in decibels (dB) or voltage and can occur due to a variety of factors. It may cause signals to become distorted or indiscernible.
What is attenuation in criminal procedure?
The attenuation doctrine
allows evidence to be admitted when the connection between unconstitutional police practice is remote or has been interrupted by an intervening circumstance
so that the violation is not served by suppression.
What is attenuation doctrine?
The attenuation doctrine holds that
evidence is admissible when the connection between unconstitutional police conduct and the evidence is remote or has been interrupted by an intervening circumstance
.
What does markedly attenuated mean?
1. Reduced in virulence or infectivity. 2.
Thin, minimal
, markedly reduced or decreased.
What are the 3 exceptions to the exclusionary rule?
Three exceptions to the exclusionary rule are “
attenuation of the taint,” “independent source,”
and “inevitable discovery.”
What is the relationship between attenuation and data rate?
What is the relationship between attenuation and data rate? Attenuation in computer networking is
the loss of communication signal strength that is measured in
decibels (dB). As the rate of attenuation increases, the transmission, such as an email a user is trying to send or a phone call, becomes more distorted.
Is attenuation good or bad?
The greater the attenuation in a circuit, then more signal will be lost. So lower attenuation cable is always better but it comes at a price. Designers must make tradeoffs between cost, availability and “good enough” designs that make sense for everyone. However,
not all attenuation is bad
.
Why is attenuation important?
Attenuation in fiber optics, also known as transmission loss, is the reduction in intensity of the light beam (or signal) with respect to distance travelled through a transmission medium. … Attenuation is an
important factor limiting the transmission of a digital signal across large distances
.
What can cause attenuation?
- Noise. Extra noise on networks, like radio frequencies, electrical currents, and wire leakage, may interfere with the signal and cause attenuation. …
- Physical surroundings. Physical surroundings like temperature, wall barriers, and improper wire installation may distort the transmission.
- Travel distance.
What is the exclusionary rule?
The exclusionary rule
prevents the government from using most evidence gathered in violation of the United States Constitution
. The decision in Mapp v. Ohio established that the exclusionary rule applies to evidence gained from an unreasonable search or seizure in violation of the Fourth Amendment.
What is an example of the exclusionary rule?
For example, if a defendant is arrested illegally,
the government may not use fingerprints taken while the defendant was in custody as evidence
. Because police would not have obtained the fingerprints without the illegal arrest, the prints are “fruit of the poison tree.”
What is an example of inevitable discovery?
The police unlawfully entered private premises and observed marijuana
. The police left the scene and went to a Magistrate to obtain a search warrant. They did not tell the Magistrate about the prior entry or about their observations made inside the premises.

How is attenuation calculated?
- To calculate attenuation (dB) simply multiply rule of thumb by round trip distance & by frequency.
- 5 MHz sound; 10 cm sound travel.
- 3.5 MHz sound; 4 cm sound travel.
What is attenuation in psychology?
1.
the lessening or weakening in strength, value, or quality of a stimulus or other factor
, for example, a medication acting on symptoms. … ATTENUATION: “Attenuation in the person’s depressive symptoms occurred when he or she began to take medication and partake in therapy.”
