The digital peak scale is not equivalent to the analog RMS scale. You can never match dBFS and dBu. dBu is volts - you measure it with a volt meter. Analog audio: positive and negative voltage. dBFS is in contrasta binary number. ...
When you want to know how much the electricity is costing you, you use watts. When you are specifying equipment loads, fuses, and wiring sizes you use the VA, or the rms voltage and rms amperage. This is because VA considers the peak of both current and voltage, without taking into acc...
Since it is the ratio of two voltages, they can be measured as peak-to-peak or RMS and with the same units. Reference voltage 1 mV. dBμV or dBuV (decibel microvolt, amplitude ratio) — absolute voltage in decibels relative to one microvolt, used to measure the signal strength in RF...
The circuit shown below has a 45.0-V rms voltage of unknown frequency. (a) What is the rms current delivered by the power supply when the frequency is very low? (b) What is the rms current delivered by the power supply when the frequency is very high? (c)A 10 ohm resistor has a ...
If you wanted the FFT output in units of dBm, you would want to use the FFT Amp Spectrum (Volts RMS) function instead. This function outputs an array of voltage values (assuming the input is an array of voltage values) that represent the voltage in each frequency bin of the FFT across...
The rectifier is an instrument to convert alternating current (AC) to direct current (DC).Answer and Explanation: The DC voltage is equivalent to RMS AC voltage. RMS refers to the square root of the average of the squares of all AC voltage values in the set. The......
As shown in the figure, a square wave and sine wave may have identical peak voltage levels but the RMS value or the root mean square value may not be identical. This aspect is what that makes a square wave particularly different from a sine wave even though the peak value may be the ...
A utility to convert between standard units of power measurement and signal strength.Instructions | Related InformationInstructionsThis calculator interconverts between dBm, dBu, dBV, VPEAK and VRMS (ANSI T1.523-2001 definitions). dBm is a power ratio relative to 1mW, dBu and dBV are voltage rati...
which are used to step up or step down the voltage levels. 230V AC is converted into 12V AC using a step-down transformer. 12V output of stepdown transformer is an RMS value and its peak value is given by the product of square root of two with RMS value, which is approximately 17V...
The sound pressure is the alternating sound pressure as RMS value. The sound pressure amplitude is the peak value of the sound pressure. The sound volume (loudness) is determined mostly by the sound pressure p and expressed as sound pressure level Lp in dB. Comparison of sound pressure level...
