Electronic devices and the components they are made of have unique properties. This is because they operate based on principles related to electricity, waves, and other physical phenomena. Knowing this and the issues these devices can encounter is necessary to develop hardware that meets specific requirements. You are likely to be asked about several of these during an interview, so be sure to review the key principles used in your designs before the interview.

William Swansen

"SNR stands for signal-to-noise ratio. It can impact a hardware design by creating interference and unwanted signals that alter the device's functions or cause other issues. SNR can be addressed by using quality components, making sure all the connections are tight, placing specific components further away from each other, and using components such as amplifiers and other devices to reduce the noise emitted by an electronic device."
