What is processing gain?
The process gain (or 'processing gain') is the ratio of the spread (or RF) bandwidth to the unspread (or baseband) bandwidth. It is usually expressed in decibels (dB).For example, if a 1 kHz signal is spread to 100 kHz, the process gain expressed as a numerical ratio would be 100,000/1,000 = 100. Or in decibels, 10log10(100) = 20 dB.
What is the meaning of gain in an amplifier or operational amplifier. Is high gain or low gain is what we try to achieved?
There are many uses for amplifiers. Some try to achieve extremely high gain such as in a radio receiver. Many try to achieve no overall gain. Examples include mixers and filters. Some only try to achieve limited gain. Oscillators try to achieve zero gain at most frequencies but unity to very high gain at the frequency of oscillation depending on the output wave form required. Basically - everything in electronics is an amplifier. The absolute gain of am amplifier is the ratio of output signal to input signal. For voltage or current amplifiers this is usually expressed as field decibels which is 20 log (out/in). For power amplifiers the gain in decibels is 10 log (output power/input power). If the gain is less than one, the same rules apply but the decibels will turn out to be a negative quantity.
Does voltage current or power affect volume in a speaker?
Power (Watts)/ Decibels (if the speaker is efficient) 2 Watts = 93 decibels 4 Watts = 96 decibels 8 Watts = 99 decibels 16 Watts = 102 decibels 32 Watts = 105 decibels 64 Watts = 108 decibels 128 Watts = 111 decibels 256 Watts = 114 decibels 512 Watts= 117 decibels 1024 Watts = 120 decibels Some Volumes to Compare 10 decibels = normal human breathing 60 decibels = normal human conversation 110 decibels = power saw, car horn, shouting in ear, 120 decibels = jet aircraft close by, emergency vehicle siren, rock concert

What is attenuation network?
Attenuation is a measure of how much loss a signal experiences when it travels down a communication medium( loss as heat, absorbed by communication medium).It is mesured in decibels Attenuation is a term that refers to any reduction in the strength of a signal, when transmitting over a long dinstance. Attenuation occurs with any type of signal, whether digital or analog. It is also called loss of signals, The extent of attenuation is usually expressed in units called decibels (dBs).
What is attenuation in decibels?
The degeneration of a signal over a distance on a network cable is called attenuation. It does not have any relation with decibels. The strength of signal just gets reduced.
What is processing gain?
The process gain (or 'processing gain') is the ratio of the spread (or RF) bandwidth to the unspread (or baseband) bandwidth. It is usually expressed in decibels (dB).For example, if a 1 kHz signal is spread to 100 kHz, the process gain expressed as a numerical ratio would be 100,000/1,000 = 100. Or in decibels, 10log10(100) = 20 dB.

What is the implication of negative voltage gain?
If the input and output are expressed in volts, then negative gain means a 180° phase shift. If the ratio of output to input is expressed in dB, then negative gain means attenuation, i.e., less power out than power in.
What is sound attenuation expressed in?
Neper/meter
How Attenuation measured?
RMS Output divided by input, usually expressed in deciBells. Depends on whether it is power or voltage being attenuated. Voltage, it's 20log(Vout/Vin) Power, it's 10log(Pout/Pin) The difference is because power is proportional to voltage squared.
Power gain of an amplifier having input gain of 20W and what is the output gain of 20mW?
The power gain of an amplifier having an input of 20W and an output of 20mW is 0.001. Expressed in decibels, that is a gain of -30db. (log2 0.001 * 3)If you meant an output power of 20MW (mega instead of milli), the gain is 1,000,000, or +60db.
What is power gain of an amplifier having input gain 20watt and output of 20mwatt is?
The power gain of an amplifier having an input of 20W and an output of 20mW is 0.001. Expressed in decibels, that is a gain of -30db. (log2 0.001 * 3)If you meant an output power of 20MW (mega instead of milli), the gain is 1,000,000, or +60db.
What is db in 3db coupler?
In a 3dB coupler, the "dB" stands for decibels, which is a unit to measure the attenuation or gain of a signal. The 3dB value indicates that the signal power is divided equally among the output ports, resulting in a 3dB loss compared to the input signal power.
The reduction in amplitude of a wave due to energy loss is called?
The reduction in amplitude of a wave due to energy loss is called attenuation. This process leads to a decrease in the intensity of the wave as it travels through a medium and is often described in terms of decibels.
What is the different between positive and negative decibel?
Negative decibels mean damping (loss) and positive decibels mean amplification (gain).
