Steven.go · 16 years ago

Bis auf ein redet oder clear Button der fehlt, ist alles okay. für 79 Cent bietet das App. leider zu wenig settings. Update der Bedienung und weitere . Wünsche mir ein update mit einzelner db Berechnung bei der zwischen Pegel dbspl dbu Pa USW. geswitcht werden kann.

Specialized and useful

scoopr · 16 years ago

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

A handy app

AnaloguEE · 16 years ago

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

Good start

Nb53 · 15 years ago

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 very useful application.

Looks like my name is taken so · 12 years ago · v1.5

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

Perfect
