Description
Need to quickly convert between various RF signal measurement units? dB Calc performs lots of decibel related conversions:
Decibel / Neper / Ratio Conversions:
Enter in either the dB, Np (nepers), power or voltage ratio, and the other values will be calculated.
Decibel / Power / Voltage Calculations:
Enter in the one known value, and the others will be calculated. Select the correct units before entering in the value. You can change the units of the displayed (calculated values) by selecting the new units. Enter in the resistance before entering in the known value.
The following units are available:
dBmW - dB ref to 1 mW power
dBuV - dB ref to 1 uV
dBu - dB ref to 0.7746 V (audio)
dBV - dB ref to 1 V
uW - microwatts
mW - milliwatts
W - watts
uV - microvolts
mV - millivolts
V - volts
RMS Waveforms Conversions:
Conversion between rms, peak, peak-peak voltage and current values for a user entered resistance. Sine, square, and triangle waveforms are supported.

A very useful application.
I find this application to be very useful in my day-to-day work as an RF engineer it's really quite nice.

Good start
A nice app but needs a lot more. I would delete the top section and expand on the middle section to include additional RF and dB conversions. It will then become a nice and handy tool.

A handy app
A handy app for E.E.'s, but personally I'd drop the Neper to make room for V1 V2 fields in addition to the ratio field.

Specialized and useful
This app was exactly what I was looking for. Quick conversion between dB based units. Very useful. Creator very responsive to feedback and requests.
