3/8-wave
1/2-wave
Answer
Problem 3—Open circuit stubs are preferred
for lines such as microstrip/stripline. True or false?
Answer
Problem 4—Multiple reflections take place between
quarter wave matching section and the load even when the
line is actually matched. True or false?
Answer
Problem 5—Shunt stubs are preferred to series
stubs for stub matching networks. True or false?
Answer
Problem 6—Suppose you have a module with two input
ports and two output ports that sorts its inputs into

lists of values?
Answer
Problem 7—How many modules would be required to
sort 16 inputs?
Answer
