Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

If a sequence of length N=32 is processed using Radix-2 FFT, how many levels of recursion will occur before reaching the base case?

💡 Hint: Think about the power of two for N.

Challenge 2 Hard

Consider an arbitrary sequence x[n] of length N=8. Derive the even and odd indexed sequences and show the step-by-step calculation for two levels of recursion.

💡 Hint: Remember how you can break it into even more parts.
