Abstract:
A transponder (1) having at least one signal channel (5, 6, 7), which signal channel (5, 6, 7) having transmission means (8, 9, 10) and at least two signal processing stages (25, 26, 27, 28, 29, 30, 31) connected to the output side of said transmission means (8, 9, 10), wherein at least one signal processing stage (26, 27, 29) is configured such that it is activatable and deactivatable, and wherein for each activatable and deactivatable signal processing stage (26, 27, 29) an associated bypass branch (32, 33, 34) being provided for bypassing the associated signal processing stage (26, 27, 29), which bypass branch (32, 33, 34) is also configured so as to be activatable and deactivatable, and wherein control means (35) are provided by which the at least one activatable and deactivatable signal processing stage (26, 27, 29) and the at least one associated activatable and deactivatable bypass branch (32, 33, 34) are activatable and deactivatable, and wherein the control means (35) and the at least one activatable and deactivatable signal processing stage (26, 27, 29) and the at least one associated activatable and deactivatable bypass branch (32, 33, 34) are so configured such that when one activatable and deactivatable signal processing stage (26, 27, 29) is deactivated the bypass branch (32, 33, 34) associated with this signal processing stage (26, 27, 29) is activated at the same time, and that when one signal processing stage (26, 27, 29) is activated the bypass branch (32, 33, 34) associated with this signal processing stage (26, 27, 29) is deactivated at the same time.
