1) Defina en que consiste ISI 20%
La interferencia entre símbolos (ISI) consiste en la interferencia de un bit o
símbolo sobre los bits o símbolos que siguen después de este. Esto se da por

Esto lo que provoca son errores en el receptor a la hora de decidir si el bit
recibido fue un 0 o 1 afectando a la señal que es recibida.
