Description

From the listing uploaded by “catappult”.

This app can accept a two port parameter matrix (in either rectangular or polar form). It will then convert the matrix in any required parameter (i.e. Z, Y, T, T', H or G). Useful for electrical/electronics engineers. Feel free to comment / suggest for improvement. Kindly let me know if you find some error.

Two Port Network APK: questions and answers

Can I install this APK over the version I already have?

Only if it is signed with the same certificate as the copy on your phone and isn't an older version. If Android says “App not installed”, the certificates differ; uninstalling your copy first works but deletes its data unless it is backed up.

Is the Two Port Network APK safe?

No one can promise that a file is safe, but some things can be checked. The source store rates this file Trusted. After downloading, check that the file's MD5 is 4579456a463c2e470631a8449ddfeefc.
