logic - Implementing 5-variable function using multiplexers -

-

If I have the 5-variable function (below) and I want to implement it using multiplexer, then I How to do (using the minimum possible multiplexer): 

  f (A, B, C, D, E) = A + CD + BD 'B'D + B'CE

This is homework, so do not provide solutions, a guide to how it works.

Thank you!

<5 5 variables with input from to 32 means 2 ** (32) multiplexer. convert these words binary numbers and keep the corresponding high. for B'CE we have: 

  ABCDX 0 1x1

This gives us 4 numbers, because We do not care 2. There are four numbers: 

  00101 = 5 00111 = 7 10101 = 21 10111 = 23

Hold inputs 5, 7, 21, and 23 high.

Repeat for the rest of the words.

c# - TypeConverter in propertygrid only converts from string, not to -

-
When the property grid is reached, only the conversion mechanism (often called) is called "Foo!" Returns the property string in the grid when I click to edit I get an exception Type.oo. Object type can not be changed to type. (Not properly translated,) What is a clue from the convert format, why not? And the error indicates that it is trying to convert to a string, not from. I think that when I want to edit this object, it will have to be converted from foo to string, and when the editing ends. Public class FooTypeConverter: StringConverter {public override object ConvertFrom (ITypeDescriptorContext Reference, CultureInfo Culture, Object Value) {New Foo (string) value); } Convert the public override object (Type the ITE DiskText Contact Reference, CultureInfo Culture, Object Value, Type Type) {Return "Foo!"; } Public override bool CanConvertFrom (ITypeDescriptorContext reference, type source type) {back true; } Public Override Bull CanConvertTo (ITypeDescrip...
