    RF sampling: aliasing can be your friend

    ** This is the fourth post in a new RF-sampling blog series that’ll appear monthly on Analog Wire ** Communication system engineers are generally obsessed with signal-integrity issues. They want a low noise system to discern very small signals. They want high linearity performance to maintain immunity to interference. And when discussing high...

    Inductive sensing: How to sense spring compression

    While most inductive-sensing applications use either printed circuit board (PCB) coils or wire-wound inductors as the sensor, inductance-to-digital converters (LDCs) can use almost any inductor as a sensor – even a spring. Springs are useful as...
