+<span size="x-large"><b> Код Хэмминга </b></span>
+
+
+В данной лабораторной работе используется код Хэмминга 7-4, другими словами, код, который нужно закодировать, имеет длину в 4 бита, в то же время выходной код будет иметь 7 бит.
+
+Программа умеет как кодировать ключевые слова, так и проверять их.
+
+<b> Режим кодирования </b>
+
+В этом режиме мы вводим код, в котором каждое "слово" имеет 4 бита. Это может выглядеть следующим образом:
+
+<tt>1010 1100 1110 0000</tt>
+
+Мы получим следующее:
+
+<tt>1100110 0111100 0101010 0000000</tt>
+
+В противном случае появится информационный блок с предупреждением: "Проверьте корректность кода".
+
+<b> Режим проверки </b>
+
+Данный режим проверяет код на ошибки. Проверка в лучшем случае пишет: "Все коды корректны". При ошибочно введённом коде, программа построчно отобразит в каких кодах есть ошибка.
+
+Пример ввода аналогичен предыдущему:
+
+<tt>1100110 0111100 0101010 0000000</tt>
+
+Результат:
+
+<tt>Все коды корректны.</tt>
+
+Если мы поменяем какой-либо бит в одном или в нескольких "словах":
+
+<tt>1100110 0011100 0101110 0000010</tt>
+
+Мы получим результат:
+<tt>
+Ошибка в коде 2 [0011100], позиция ошибки 2, корректный код: [0111100]; 
+Ошибка в коде 3 [0101110], позиция ошибки 5, корректный код: [0101010]; 
+Ошибка в коде 4 [0000010], позиция ошибки 6, корректный код: [0000000];
+</tt>
+
+
+<span size="x-large"><b> Затухание сигнала </b></span>
+
+
+Лабораторная работа подразумевает рассчитать для каждого из девятнадцати значений частоты реактивного сопротивление конденсатора X<sub>c</sub>, напряжение сигнала на стороне приёмника информации V<sub>п</sub> и коэффициент затухания сигнала ζ.
+
+Значения вводятся согласно исходным данным для расчёта затухания сигнала. Значения можно вводить как с ",", так и с ".".
+
+При вводе одних и тех же данных без изменений, будет показано предупреждение и операция расчёта не будет выполнена. Можно не менять данные в случае частоты, чтобы обновить данные расчёта в соответствии с новыми (К примеру, в случае длины провода, или сопротивления провода).
