What's New

Ω New Tools:
• Basic Tools: two more T pad and two more Pi Pad tools. Adding symmetric T/Pi pad circuits and additional T/Pi pads, which calculate the return loss and the attenuation based on the values of the input resistors and the impedance of the system.
• Frequency Tools: new Fourier series tool. Illustrates how the Fourier expansion works (the number of harmonics can be set as desired within the range of 0 - 50).

Ω Audio Function Generator:
• Scope View optimisations (moving the waveforms, calculating the cycle duration)
• BPM feature optimisations (adding fine-tuning and slider)
• Audio Engine optimisations for all non-sine signals
• Improved visualisation of the phase view popover
• Variable sweep time calculation fix

Ω Added option to copy numbers from calculated fields
Ω Better readability of the control elements in Dark Mode
Ω Fixed the diagram of the center tapped transformer rectifier (rectifier tools)
Ω Fixes and improvements all over the App
