The symbol is an abbreviation for decibels relative to one milliwatt, where one milliwatt (1 mW) equals 1/1000 of a watt (0.001 W or 10 -3 W). This unit is commonly used in test laboratories. The dBm increment is based on the decibel, a logarithm ic measure of relative power. Suppose a signal has a power level of P mW. Then the signal strength in dBm, symbolized S dBm, is: S dBm = 10 log 10 P. A 1-mW signal has a level of 0 dBm. Signals weaker than 1 mW have negative dBm values; signals stronger than 1 mW have positive dBm values.
Memorial Day, originally called Decoration Day, is a day of remembrance for those who have died in service of the United States of America. Over two dozen cities and towns claim to be the birthplace of Memorial Day. While Waterloo N.Y. was officially declared the birthplace of Memorial Day by President Lyndon Johnson in May 1966, itâs difficult to prove conclusively the origins of the day.
