A receiver operates with a noise figure of 2 dB and a bandwidth of 5 MHz at 290 K. Calculate the noise floor. Then, discuss how this affects its ability to detect signals.
💡 Hint: Don’t forget to use Boltzmann's constant and consider the relationship with bandwidth.
Design a hypothetical RF system that improves linearity by 5 dB without adding noise. Discuss potential trade-offs in terms of complexity and cost.
💡 Hint: Think about component selection and system architecture.
