Field: Telecommunications (Electrical engineering)
Classification: CPC G  H | IPC H

Claim 3:
4. A detector comprising:
a detection switch configured to obtain an initial signal; and
a signal processor configured to process a detection signal comprising the initial signal in real-time;
recording, as a start point, a moment at which a level of the detection signal is converted;
detecting a status of the detection signal at a current moment;
comparing a current time width with a maximum interval width of pre-set interference signals, which comprise blocking interference signals or application interference signals; and
determining and recording signal levels from the start point to the current moment;
wherein, when the detection signal is converted from the low level to the high level;
the moment at which the level is converted is recorded as the start point;
a level status of the detection signal at the current moment is detected in real time; and
the current time width of the high level signal is compared with the maximum interval width of the blocking interference signals;

wherein:
if blocking is determined, the high level is changed to the low level; and
if no blocking is determined, the detection signal is set to the high level; and
the moment at which the level is converted is recorded as the start point;
a level status of the detection signal at the current moment is detected in real time; and
the current time width of the low level signal is compared with the maximum interval with of the application interference signals;

wherein
if an interval is determined, the low level is changed to the high level; and
if no interval is determined, the detection signal is set to the low level.
