A continuous periodic signal with a period of 200 seconds was digitized using a sampling period of 62.5 seconds and 16 bits / sample. a.- Justifiably determine if the discrete signal obtained is periodic. b.- If the signal is requantized to 5 bits / sample using the fixed scale factor technique (to store it), determine the number of bits that the signal occupies, knowing that two periods are stored and that the scale factor occupies 6 bits in the generated file c.-Write the equation of the discrete signal
