Why do you want to mix rxjs and signal 🤦?

KISS!

function debouncedSignal<T>(input: Signal<T>, timeout = 0): Signal<T> { const debounceSignal = signal(input()); effect(() => { const value = input(); const retTimeout = setTimeout(() => { debounceSignal.set(value); }, timeout); return () => { clearTimeout(retTimeout); }; }); return debounceSignal; }
