Cheers for the input. One last thing, the value given is a quiescent power dissipation value? I don't think its dynamic. If it is quiescent then it has to 5mW total.
The trouble I have is calculating power for one gate input using P=IV, when the VIH is a minimum value.
For a HIGH input power, 2*20*10^-6= 0.04. For 7 HIGH inputs that is 0.28mW
For the 3 LOW inputs, (100*10^-6*0.8)*3= 0.24mW ...however
However the Power dissipated or PD=supply voltage Vcc...
Using the ALS figures from the tables
(a) I can see three gate inputs supplied by the output of gate 1. The three gate inputs of gates 2,3 and 4 are LOW and at 100uA each so IOl at gate 1 is 300uA or 0.3mA.
(b) Propagation delay per gate is calculated as (t1+t2)/2 where it switches from HIGH...
Homework Statement
For the ALS logic circuit, estimate:
(a) the current IOL
(b) the delay in a 1-to-0 transition at one of the inputs of GATE 1
appearing as an effect at the output of GATE 5.
(c) the total power consumed by the circuit in a quiescent state.

Thanks for your responses guys, this is essentially the circuit if we assume the source input is actually a transformer with a 10:1 ratio at 230 rms at 50 Hz;
I can understand where your coming from about adding the diodes to the secondary rms voltage; the equation I used is a design equation...
The peak secondary voltage is the desired output VO + the diode voltage drops. i.e 23V + 1.4V. The question has not given me the values of the forward voltage drops across the diodes, I've assumed them. I know that when 2 are conducting, the other pair are reversed biased or "off."

LHomework Statement
A Transformer with a stepdown ratio of 10:1 is supplied with a 230 RMS voltage at 50hz connected to a four diode full wave bridge rectifier and smoothing circuit. If the smoothing capacitor value is 1000uF and the load resistance RL is 25 ohms, find:
the secondary winding...
