Analogue electronics (American English: analog electronics) are electronic systems with a continuously variable signal, in contrast to digital electronics where signals usually take only two levels. The term analogue describes the proportional relationship between a signal and a voltage or current that represents the signal.
Functional analogs (or functional analogues) are entities (models, representations, etc.) that can be replaced, to fulfill the same function. When the entities in question are formally represented by black boxes , the concept of analog is related to "same behavior": they take the same output sequence when submitted to the same input sequence.
DMPX (3,7-dimethyl-1-propargylxanthine) is a caffeine analog which displays affinity to A 2 adenosine receptors, in contrast to the A 1 subtype receptors. [1] DMPX had 28× and 15× higher potency than caffeine in blocking peripheral and central NECA-responses. The locomotor stimulation caused by DMPX (ED 50 10 μmol/kg) was similarly higher ...
While the words analog audio usually imply that the sound is described using a continuous signal approach, and the words digital audio imply a discrete approach, there are methods of encoding audio that fall somewhere between the two. Indeed, all analog systems show discrete (quantized) behaviour at the microscopic scale. [52]
This is a list of cocaine analogues.A cocaine analogue is an (usually) artificial construct of a novel chemical compound from (often the starting point of natural) cocaine's molecular structure, with the result product sufficiently similar to cocaine to display similarity in, but alteration to, its chemical function.
A structural analog, also known as a chemical analog or simply an analog, is a compound having a structure similar to that of another compound, but differing from it in respect to a certain component. [1] [2] [3] It can differ in one or more atoms, functional groups, or substructures, which are replaced with other atoms, groups, or ...
A cup of cooked pasta provides about 7 to 8 grams of protein while 1 cup of cooked gnocchi only has 2 to 3 grams of protein, she explains. Neither gnocchi nor pasta will be the major source of ...
This is a list of fentanyl analogues (sometimes referred to as Fentalogs), [1] [2] [3] including both compounds developed by pharmaceutical companies for legitimate medical use, and those which have been sold as designer drugs and reported to national drug control agencies such as the DEA, or transnational agencies such as the EMCDDA and UNODC.
