E.g.,
n = 0:0.01:10;
x = 3*cos((2*pi*3*n)/25);
plot(n,x)
grid on
xlabel('n')
ylabel('x')
title('x = 3*cos((2*pi*3*n)/25)')

a) Señales periódicas. Determine si las siguientes señales son periódicas. En caso afirmativo, especifique su frecuencia fundamental.
i) 𝑥(𝑛) = 2exp[𝑗 ( 𝑛 6 − 𝜋)]
ii) x(𝑛) = cos ( 𝑛 8 ) cos( 𝜋𝑛 8 )
Su Apoyo porfavor
