6. Let us assume that for the logic states in a circuit,
(i) 1 defines by an output signal voltage 5 V and
(ii) 0 defines by the output signal voltage 0.4 V.
Assume output logic state changes every ms in the in sequence 1, 1, 0, 1, 1, 0, 0 and
0. Show the waveform within the period 0 to 8 ms.
7. Let us assume that in the logic signals from a circuit,
(iii) 1 means the output signal is of voltage 12 V and
(iv) 0 means the output signal is of voltage +12 V.
Assume output logic changes every ms in the in sequence 1, 1, 0, 1, 1, 0, 0 and 0.
Show the waveform within the period 0 to 8 ms.
