Hi,
For a clock signal the minimum clock low period,minimum clock high period and rise and fall times are specified. The duration of one cyle is the sum of all the above. Generaly clok high and clock low minimum periods are more or less equal. Hence at 50 % duty cycle maximum frequency of...
Re: Question on Phase Neutral connection
You are right. Neutral is the return path. The current going from phase is returning to neutral through the load. But generally AC distribution is 3 phase. in this connection all the 3 phase currents return through the neutral. The currents are having...
In the circuit shown there is no ground loop is formed as long as the sensors are isolated. But in the circuit no biasing arrangement is shown for photo conductive type sensor.
1. Not necessary
2. saturation is the condition Ic< Beta *iB
3. yes with Rc* Beta > Rb
4 yes switch is on when base is tied to vcc ; off when base is tied to ground
