Definition 1:
In this case, regardless of where the signal comes from, we define the signal source as 16 dBmV (76dBuV), a 65 dB CTB, and a 50 dB carrier-to-noise ratio (according to the national first-level optical cable signal distortion standard). 。
Definition 2:
Signal source refers to the radio head, high frequency head, recording card holder, video card holder and other devices. Microcomputer and auxiliary equipment complete signal extraction, digital-to-analog conversion, digital signal processing, digital-to-analog conversion and other functions.
Definition 3:
Signaling events are called signal sources, including processes, kernels, interrupts and anomalies. Signal processing must be completed by the process of receiving the signal, which allows the process to ignore the signal, block the signal, send the signal to the default processing of the kernel and process the signal itself after receiving the signal.
Definition 4:
Fault judgment method caused by sensor and weighing instrument: pull signal line from weighing instrument and connect it with special analog sensor (also called signal source). If the weighing instrument is stable at this time, it shows that the instrument is good and the fault occurs in the sensor.
。
Definition 5:
Therefore, all the instruments and equipment related to measurement can be divided into two kinds on the whole. One is the equipment that provides the displayed information, called signal source. The other is the instrument that acquires information and transforms, analyses, processes and displays it, called measuring instrument and equipment.
