Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

A band-pass filter has a peak response at 100 MHz and a bandwidth of 20 MHz. Calculate the lower and upper cutoff frequencies.

💡 Hint: Think about how to find the range around the peak frequency based on the bandwidth.

Challenge 2 Hard

Given that a filter has a return loss of 30 dB, what percentage of the signal is reflected back?

💡 Hint: Consider the formula connection between return loss and reflected power.
