Inhibitor(redirected from COX-2 i)
Also found in: Dictionary, Thesaurus, Medical, Legal, Wikipedia.
a circuit having m + n inputs and a single output, at which a signal can appear only when there are no signals on the m inputs (inhibiting). The other n inputs (principal) form one of the two logic connections, “AND” or “OR.” Inhibitors are used extensively in computers. They are very often understood to be a circuit having a single principal input and a single inhibiting input. A signal appears at the output of such a circuit when a signal is present on the principal input but there is none on the inhibiting input. Such an inhibitor is called an anticoincidence gate; its conventional representation is given in Figure 1.
