Class 341 :: CODED DATA GENERATION OR CONVERSION

Definition

GENERAL STATEMENT OF THE CLASS SUBJECT MATTERThis is the generic class for

(a) originating or emitting a coded set of discrete signals or

(b) translating one code into another code wherein the information signal content remains the same but the formats may differ. For classification herein, at least one of the codes must be a set of pulses or digits and electrical in nature.

LINES WITH OTHER CLASSESExcluded from this class is analog to analog conversion. See References to Other Classes, below, for examples of other classes containing this subject matter.

Included in this class (341) is subject matter relating to codes, per se, such as Morse codes, grey codes. Excluded from this class are coded records and coded record readers. See References to Other Classes, below,Combinations of an optically encoded shaft wheel and a photocell absent any signal processing circuitry are classified elsewhere. See References to Other Classes, below.

Code converters which may be utilized in pulse or digital communication systems, Class 375, are classified in this class (341).

A. The combination of the subject matter of this class (341) and another art environment is generally classified with the art device where the environment is significant by virtue of the claimed relationship. For example:Coding and decoding for cryptographyCoding and decoding for error detection or correctionCode transmitters specific to telemetry.

Data compression and expansionMicrowave devices.

Radiowave beacons.

Radar generation, conversion or systemsB. Pulse generation or conversion which is not unique to communications are classified in the appropriate classes. For example:Pulse demodulation, per se.

Pulse generation.

Pulse modulation, per sePulse wave conversion systems; i.e., sine wave to pulse waveSee References to Other Classes, below, for appropriate class references.

This class is structured into 14 main divisions. See Subclass References to the Current Class, below.
