Sr.No	Parameter	FDM	FEM	MOM
1.	Domain used	Frequency & time	frequency	frequency
2.	Simplicity	Simple	Conceptually difficult	Simple
3.	Resultant matrix	sparse	Sparse	Full matrix
4.	Equation type handled	Large	Large	Small
5.	Memory Required	Large	Large	Small
6.	Boundary	Used for finite geometry	Used for finite geometry	Used for infinite geometry
7.	Principle	Geometry divided into mesh	Geometry divided into specific shape units	Geometry divides into basic blocks, which has standard solutions
8.	CPU time required	Large	Medium	Small
9.	No. of equation resulted	Many	Many	Few equations
10.	Wideband	Not best	Not best	Good
