Разработать и отладить программу генерации звукового сигнала. Генерация должна прекращаться с нажатием любой клавиши. 
...Модернизировать программу, обеспечивая изменение тона сигнала при каждом нажатии клавиши. Определить с помощью модернизированной программы значения коэффициента пересчета таймера, при которых обеспечивается высший и низший тон услышанного звукового сигнала.
