A DB-9 connector is a 9-pin connector, approximately 2cm long by 0.75cm wide, with two rows of pins or sockets, a row of 5 and, a row of 4, hence 9 pins total. It is often used in low-speed data communications such as RS-232, and is the connector on personal computers since the IBM PC-AT used for COM ports. There are larger versions with 15 pins, called DB-15 and used for game ports and 10Base5 network AUIs, and 25 pins, called DB-25 and used for earlier COM ports and printer ports among other things.

DB701 is lighter (They are German Railway Colours - Deutsche Bahn = DB)
You must find a resistance value for 0 dB as reference. If 1 Ohm = 0 dB then 10 ohms = 20 dB and 100 ohms = 40 dB.
dB mean Decibel.
yes it = 1

The threshold of hearing is 0 dB. The threshold of pain = 137.5 dB.

No, it is 10 times louder. dB is a logarithmic scale; every 10 dB, the intensity increases by a factor of 10. Thus, 10 dB is 10 times louder than 0 dB, 20 dB is 10 times louder than 10 dB, and 30 dB is 10 times louder than 20 dB.No, it is 10 times louder. dB is a logarithmic scale; every 10 dB, the intensity increases by a factor of 10.
