Differences between high-frequency and power-frequency machines

The power frequency machine is a traditional X-ray equipment that uses 50Hz AC as the power supply of High Voltage Generators. We know that the composition of X-ray machine (or X-ray equipment) can be roughly divided into two parts: X-ray Generator (X-ray source) and auxiliary equipment. The following discussion will confuse the x-ray machine with the X-ray

, which is the full-scale relative level (DBFS). Because a maximum value of 0 is specified, the full-scale relative level of the signal actually processed by an ADC is negative. The dBFS of a 12-bit ADC chip: DBFS = LOG10 (sample signal/1111 1111 1111). Therefore, Fin = -1dbfs is often seen in the ADC data document, so that the -1DBFS fin in this case is equivalent to 0.8913 of the full scale input amplitude, as calculated from the above formula. 8. Two-tone

ADSL divides the high frequency of telephone lines into many tones.

ADSL divides the high-frequency part of a telephone line into many tones. Each tone carries a certain bit bandwidth, and the total bandwidth that all tones can carry is the maximum bandwidth of this ADSL line. Each tone has a certain background noise. After the bandwidth occupied by this background noise is removed, th
