The input will be a l-bit time series indicating the Morse code pulses as shown in Fig. 2. This time series will be parsed into a set of pulse widths (durations) using a finite state machine: each 1' pulse is separated by a short '0 gap, while sets of pulses defining a single character are separated by a long '0' gap Long pulse: dah Short pulse: dit Short gap: between pulses Long gap: between letters time Figure 2: Input pulse timing diagram for the morse code sequence:-.
