Method and system for detecting non-linear devices
To assist with the detection of unfiltered device(s), a system observes how the received noise changes between two links as the transmit signal is changed. Harmful unfiltered nonlinear devices will generate significant noise that depends on the transmitted signals; therefore, this additional noise can be quantified to some extent by comparing the observed noise for two different transmit signals. The total noise can be determined from the SNR if the received signal is known. The received signal may be read directly in some non-standard systems, or it may be determined from the known transmit signal and channel attenuation, which is sometimes the case in standard-compliant links, but often with a relatively large error. To circumvent this problem, certain embodiments of this invention only consider the change in noise between two links with the same channel attenuation. This differential comparison makes it unnecessary to accurately know the channel attenuation. |

A method (300) and apparatus (200) are provided for operating a portable pager. The method and apparatus eliminate channel noise between paging tones and voice messages.

Once the carrier signal is re-established followed by the delayed timer expiration, the carrier squelch is removed. The speaker remains on during both signaling squelch and carrier squelch. Hence, paging tones are heard, channel noise is silenced, and then voice messages are played. |

A system for automatically modifying source code to accommodate a software migration receives a software codebase a software codebase that supports international classification of diseases, ninth revision (ICD-9) codes and that contains a plurality of lines of source code, receives a codebase impact assessment report identifying each impacted line of the plurality of lines of source code in the codebase, each impacted line requiring modification in order to support migration from ICD-9 codes to international classification of diseases, tenth revision (ICD-10) codes, and automatically modifies the codebase by modifying each impacted line of source code identified in the codebase impact assessment report so that the modified codebase supports migration from ICD-9 codes to ICD-10 codes. |
