A adrianvon Member Nov 6, 2014 #1 Hi all, Am I right if I say that: Signals with T made from a rational number is a periodic signal ? and Signals with T made from irrational number is a non-periodic signal ? If so, why in the example linked below it is states that the signal with T = pi is a periodic signal when pi is an irrational value?
