Q1
An audio message is sent through a noisy relay system 5 times (each relay receives and forwards the signal). In the analog method, each relay amplifies the waveform (and any noise on it). In the digital method, each relay re-times and regenerates the 0/1 pulses and uses error detection to flag corrupted packets. What will you most likely hear after 5 relays if the noise level is moderate (below the digital failure threshold)?
