For me, the three easiest are: Fakie shove-it. Doesn't require an ollie, if you're comfortable riding fakie this is a very natural way to spin the board. Pop shove-it. A little tougher, since it requires coordination with an ollie, but still a pretty easy flip trick. Kickflip. Much more natural than a heelflip, IMO.
The expression dBm is used to define signal strength in wires and cables at RF and AF frequencies. 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.
