Which action should you take?

Choose only one option

Low-power modes reduce energy consumption, extending battery life in portable aerospace systems without compromising performance

Low-power modes can only be applied to communication peripherals

Low-power modes only apply to consumer devices, not defense systems

Low-power modes reduce overall system performance and should be avoided

Question 3: In embedded systems for aerospace, how do you select the appropriate PCB materials to ensure optimal performance and reliability in harsh environments?

Which action should you take?

Choose only one option

By using standard PCB materials without considering environmental factors

By using generic materials suitable for low-end applications

By choosing high-quality, temperature-resistant PCB materials like FR4 or polyimide with appropriate ratings
