Releasing Couplings Designer 1.3 for iPhone and iPad!
Get it at the App Store, new users may also want to try Couplings Designer Lite for free.
Features – Tutorials – Documentation
Features and bug fixes in this version:
- support for non-resonating nodes, NRNs*
- easily toggle a node to behave as a resonating or non-resonating node
- cascade designs with NRNs or resonating nodes for a modular design
- new general synthesis seeding interface with easier access to user defined zeros and response/matrix preview
- topology transformer now performs automatic retrial if it fails, dramatically increasing the success rate for a transformation to converge
- added next/previous buttons to easily switch between goals, zeros and cascaded designs
- added fine/normal/coarse tuning sensitivity option
- better convergence during optimization
- fixes a bug that made symmetrical couplings non-symmetrical and treated diagonal pairs as individual couplings during optimization, the optimizer is now about 2X faster
- fixes a bug that changed the sign of couplings when cancel was chosen in the matrix user interface
- fixes bugs related to scaling response plot axes
* Non-resonating nodes, NRNs, are used to create new advanced topologies that are modular, individual zeros are easily tuned, less sensitive or more compact than all-resonator designs. In addtion, it is possible to implement N zeros without direct source-load coupling which allows reduced filter orders for lower loss, size, complexity and sensitivity.
Hi Goran,
Thanks for the update, version 1.4 is great and thank you for your efforts – great app
