The ability of a receiver to select the desired signal and reject unwanted signals.
A detector's ability to detect police radar while ignoring the presence of such devices as automatic garage door openers and microwaves, which may operate on closely neighboring frequencies. A good radar detector offers high selectivity as well as being highly sensitive.
The ability to focus on sounds. A dozen separate sounds reach the ears at any given moment and under normal circumstances we have the ability to focus on any one of them. A hearing impairment can cause a loss of selectivity.
Tuner specification describing the tuner's ability to reject unwanted stations. Good selectivity is important to those who live in cities,where stations are closely spaced on the broadcast spectrum.
The ability of the receiver to select the station it is tuned to, from all the others close to it on the dial/display.
The ability of a device to distinguish the signal from the background.
The measure of a receiver's ability to reject interfering signals at frequencies near the operating frequency.
The word selectivity describes a drug's ability to affect a particular cell population in preference to others. As part of the current state of art in the search for new therapeutic agents, the property of selectivity is a mode of action thought to have a high degree of desirability.... Selectivity is generally a worthy property in a drug because a drug having high selectivity may have a dramatic effect when there is a single agent that can be targeted against the appropriate molecular-driver involved in the pathogenesis of a disease. Promiscuous drugs compared to selective drugs (promiscuity can be a virtue) Simon K Mencher and Long G Wang, BMC Clinical Pharmacology 2005, 5:3 doi:10.1186/1472-6904-5-3 [Go to source
How well a radio can reject signals from a station that is immediately adjacent on the dial to the station that you are trying to listen to.
the ability of the device to measure one chemical component in the presence of others in the sample. For example ion-selective electrodes are not 100% ion-specific. Most are sensitive to some other ions to some extent. Some ISEs cannot be used in the presence of certain other interfering ions or can only tolerate very low contributions from these ions. Special techniques are available for removing or compensating for interfering ions
A measure of a tuner's ability to receive stations at closely spaced frequencies without mutual interference.
The ability of a radio tuner to select or separate stations transmitting on nearby frequencies. By reducing the IF (intermediate frequency) bandwidth to sharpen selectivity, there may be a tradeoff in the form of increased distortion. Some sophisticated tuners provide switchable selectivity so that when two adjacent stations are required to be separated, users may do so by choosing narrow IF selectivity, at other times reverting to wide selectivity to benefit from the natural reduction in distortion.
The ability of the bioanalytical method to measure and differentiate the analytes in the presence of components that may be expected to be present. These could include metabolites, impurities, degradants, or matrix components.
ability to target and capture fish by size and species, allowing by-catch of juvenile and non-target species to escape unharmed.
Many reactions can potentially occur in any real catalyst systems. Selectivity is the measure of the ability of the catalyst to promote desired reactions without affecting those that are not desired.
A measure of a radio receiver's ability to isolate a specific frequency at closely spaced frequencies without mutual interference.
Similar to capture ratio, but deals with signals which are broadcast on frequencies very close to the one selected.
refers to a gas detector's ability to select one type of fuel gas from a mixture of fuel gases and other pollutants. Most gas detection technologies today are not selective. Laser technology offers the potential for selectivity.
Ability of receiver to reject transmissions from frequencies other than the specific one to which it is tuned.
radar detector 's ability to differentiate between non-police radar signals and the real thing.
The ability of a type of gear to catch a certain size or kind of fish, compared with its ability to catch other sizes or kinds.
Charistic of a circuit to discriminate between wanted and unwanted signals.
Tuner specification which defines the tuner's ability to reject adjacent station interference.
A measure of how well a filter passes certain frequencies and rejects others. The narrower the bandwidth, the greater the selectivity.
