there are a hotel and they want to control the content of channel .
there are 2 group of rooms , some rooms are allowed to watch VHF and some rooms allowed to watch VHF and UHF.
the allowed room may be changed, one day may be 40% of rooms allowed and one day may be 80% of rooms allowed.
hotel central ANT. for all room . ( Each room have 1 coaxial cabel)
I want to build a circuit that :
1- when circuit active , the user of room not able to watch UHF ( only can watch VHF)
2- when circuit is not active , user can see VHF and UHF channels.
