The decibel is defined as dB and is a logarithmic unit used to describe a ratio such as power or voltage. A value of this magnitude indicates that the signal will be clearly readable and have little effect on the overall transmission time. ... A high gain antenna is necessary on Earth to keep the sizes of the antennas on the cycler within the ...

Friday evening, I had time to make on 3 cm three test QSOs with OK2AQ, PA0HRK for initial #64 and IK6CAK. The antenna RX performed brilliantly; the measured parameters of Sun noise = 14.6 dB and Moon noise = 2 dB are exactly as calculated from the VK3UM calculator. It's the first system I've been within a tenth of a decibel from a calculation!

Apr 13, 2009 · An Absolute Threshold is the lowest amount of stimulus needed to notice it 50% of the time. For example, you turn down the radio to a point where you only hear the faint sound half the time. Then that loudness (decibel) is your absolute threshold for sound.

Active Noise Control - EDGE
Typically most decibel meters will have the option for measuring sound using this scale. Overview of Active Noise Control: Active noise control is the creation of a pressure wave that is 180 degrees out of phase of the targeted sound wave that is to be attenuated.

Decibel Voltage Gain. The measure of voltage gain of devices such as amplifiers or the length of a transmission line is called a decibel. If is the output voltage of a device and is the input voltage, the decibel voltage gain is given by . Find the db gain of an amplifier whose input voltage is 0.71 volt and whose output voltage is 20 volts. Ex 7:
