Definitions for "Coded"
A way to attempt to preserve a person's confidentiality. For example, instead of using a person's full name, their identity could be "coded" to a number, to make it somewhat anonymous. The researchers would be able to "uncode" this information if they needed it, because they would know whose sample belonged to which code.
An audible or visible signal conveying several discrete bits or units of information. Notification signal examples are numbered strokes of an impact-type appliance and numbered flashes of a visible appliance.
