7 digital signals read from the file (stored as char type), output signal is the current value of the input signal is 2 and 2 times before
The logic of the combination. With the screen and the file output signals, respectively, using character represents the simulation output waveform. The output
Results by the existing function intf1 (char d2, char d1, char d), intf2 (char d2, char d1, char d)
Function of input parameters is given d2 and d1, d respectively expressed in low seven 7 road 2 times before signal and current signal
