Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

You have a communication channel with a bandwidth of 5 kHz and an SNR of 30 dB. Calculate the maximum theoretical capacity of the channel.

💡 Hint: Use a calculator for log calculations.

Challenge 2 Hard

If increasing the bandwidth from 20 MHz to 40 MHz doubles the data rate, what happens to the SNR if we hold the channel capacity constant?

💡 Hint: Reevaluate the relationship in the capacity formula.
