Основная и единственная цель этой маленькой программы – создание различных цифровых сигналов.
В радиолюбительском деле зачастую полезно иметь генератор сигналов заданной частоты и формы для тестирования или проверки различных узлов радиоаппаратуры. Программа Digital Signal Generator является простым виртуальным генератором сигналов различной формы и частоты, получаемых благодаря работе звуковой карты персонального компьютера. Также данное приложение проводит спектральный анализ различных типов волн.
Digital Signal Generator включает в себя генератор синусоиды, генератор прямоугольных импульсов, генератор треугольных импульсов, генератор белого шума, генератор биения и генератор синусоидальной развертки. Тип полезного сигнала можно выбирать напрямую или через вспомогательное меню программы. В скромных настройка
