A Bypass Capacitor is used to bypass high frequency signals and noise from power supplies. This prevents issues with Electromagnetic Interference (EMI). The picture below shows an example of bypass …
This tool calculates the Amplifier (or Amp) Output Power (Watt) required to provide a specified Sound Pressure Level (SPL) at a distance away from the speaker. Are you interested in …
Use this calculator to find the maximum peak Sound Pressure Level (SPL) of a speaker. Enter: Formula SPLMax = Sensitivity + 10*Log10(PS/PD) Where Example Calculation A speaker has a sensitivity …
This tool calculates the combined Sound Pressure Level (SPL) due to any number of sources. (Sometimes sound is referred to generically as noise. From that standpoint this also serves as …
This tool calculates the Resolution Bandwidth (RBW) of a Fast Fourier Transform. It also includes the effect of decimation or further downsampling of the digitized signal. Enter: FFT Resolution Formula …
This tool converts a dB (deciBel) value to a voltage ratio. Volt to dB Formula V = 10PdB/20 Where and Example Calculator For a dB value of 3, the voltage …
The crest factor of a waveform is given by the ratio of the peak to RMS amplitude level Enter Formula CF = Vpeak/VRMS Example Calculation If the peak value is …
This tool calculates the dB (deciBel) equivalent of a voltage ratio. Enter dB to Volt Formula PdB = 10*Log10((Vout2/Rout)/(Vin2/Rin)) Example Calculation If the output and input voltages are 2 V …
A question that comes up often is What amplifier should I use with my subwoofer? ⚙ We created a tool to answer this question. It gives you the specifications for …
This tool calculates the total power consumption of a set of subwoofers. It also gives the amplifier requirements to drive these speakers. Enter the wattage of the speakers with each …
