dbmv การใช้

• Widely used in television and aerial amplifier specifications . 60 dB?V = 0 dBmV.
• TEV readings are measured in dBmV . TEV pulses are full of high frequency components and hence the earthed metalwork presents a considerable impedance to ground.
• Downstream input to each cable modem of + 5 dBmV + /-2 dB . Due to the non-existence of any real input AGC, the lack of a re-modulating frequency translator and lack of upstream transmit power control, the tight receive level range accommodated upstream path variation.
