Challenge Problems
Push your limits with challenges.
Question 1
You are tasked with designing a transmitter that must convert a 150 MHz IF signal to an RF signal of 2.5 GHz. What must be the frequency of the LO signal?
💡 Hint: Apply the same IF + LO = RF relationship.
Question 2
Explain the consequences of poor filtering in the up-conversion process and how it affects communication.
💡 Hint: Consider the role filtering plays in protecting the quality of the transmitted signal.
