Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

How would you calculate the effective bandwidth of an FM signal with a frequency deviation of 100 kHz and a maximum modulating frequency of 20 kHz?

💡 Hint: Remember to account for both the deviation and maximum frequency.

Challenge 2 Hard

Given a digital signal using PSK with 4 states, calculate the amount of information transmitted per symbol.

💡 Hint: Think about the binary logarithm for states to find bits.
