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 If you have any questions or suggestions, please feel free to email us at tom@ee-toolkit.com.

Ω Audio Scope: • major re-design of the controls and the FFT mode. In FFT mode, the frequency of the signal with the highest amplitude is now displayed. Ω Audio Function Generator: • now supporting 3x16 frequency presets, all fully customisable. Use the arrow buttons to switch between them or just slide the controls. • new setting to change the frequency sliders step size (0.01 – 100).

Ω Function Generator • Frequency Sweep: added new sweep option. You can now choose between fixed and variable frequency sweeps. A custom sweep step size (Hz) and a custom sweep step duration (s) can be freely selected. This gives you a whole new way to customise your frequency sweeps! • repeated Play/Pause caused R+L signals going out of phase in some cases. This is now fixed. • change popup styles Ω SBC Tools • added new section for Espressif Systems modules and boards • updated datasets of all the other SBC Tools Ω PCB Trace Width Tools • added option to enter a custom ρ (Rho) value Ω Smaller fixes and improvements all over the App
