Selectivity is a measure of the performance of a radio receiver to respond only to the radio signal it is tuned to (such as a radio station) and reject other signals nearby in frequency, such as another broadcast on an adjacent channel.
When the vehicle is moving at low speed or the propeller is rotating at high speed, the advance ratio is a low number. The advance ratio is a useful non-dimensional quantity in helicopter and propeller theory, since propellers and rotors will experience the same angle of attack on every blade airfoil section at the same advance ratio regardless ...
The ratio of (a) total received power, i.e., the signal to (b) the noise-plus-distortion power. This is modeled by the equation above. [2] The ratio of (a) the power of a test signal, i.e. a sine wave, to (b) the residual received power, i.e. noise-plus-distortion power. With this definition, it is possible to have a SINAD level less than one.
17α-OHP is an agonist of the progesterone receptor (PR) similarly to progesterone, albeit weakly in comparison. [5] In addition, it is an antagonist of the mineralocorticoid receptor (MR) [6] as well as a partial agonist of the glucocorticoid receptor (GR), albeit with very low potency (EC 50 >100-fold less relative to cortisol) at the latter site, also similarly to progesterone.
The short circuit ratio (SCR) is an indicator of the strength of a network bus about the rated power of a device and is frequently used as a measure of system strength. A higher SCR value indicates a stronger system, meaning that the impact of disturbances on voltage and other variables will be minimized.
There are two ways of measuring ACPR. The first way is by finding 10*log of the ratio of the total output power to the power in adjacent channel. [2] The second (and much more popular method) is to find the ratio of the output power in a smaller bandwidth around the center of carrier to the power in the adjacent channel.
In medical testing with binary classification, the diagnostic odds ratio (DOR) is a measure of the effectiveness of a diagnostic test. [1] It is defined as the ratio of the odds of the test being positive if the subject has a disease relative to the odds of the test being positive if the subject does not have the disease.
Eye diagram showing an example of two power levels in an OOK modulation scheme, which can be used to calculate extinction ratio. P 1 and P 0 are represented by (binary 1) and (binary 0) respectively. In telecommunications, extinction ratio (r e) is the ratio of two optical power levels of a digital signal generated by an optical source, e.g., a ...
