    В каком диапазоне частот должно работать устройство? Каков выходной ток?

    Добрый день.

    1.Какой тип нагрузки (активный реактивный)?

    2.Диапазон частот для работы устройства?

    3.Диапазон изменения роста амплитуды (мин - макс)?

    4.Предел изменения пауз в сигнале?

    5.Тип регулирования дискретный (цифровой) или аналоговый?

    6.Допустимый уровень шумов в сигнале?

    7.Какая схема формирования предпочтительней- цифровая или аналоговая?

    Небольшое замечание - функция exp(x) стартует из бесконечности, в аналоговом исполнении будет означать шумовое возбуждение импульса, что не айс. Надо вероятно наложить на экспоненту небольшой линейный добавок, чтобы избежать нестабильности.

    В цифровом варианте можно взять микроконтроллер с DAC и запрограммировать любую форму сигнала, но решение явно не бюджетное.

    Аналоговое решение хорошо представляю (4 ОУ, несколько транзисторов...), но увы, я не в Украине..
