To look at CMRR above 1 kHz, you might use R 100c ~ 2k to give good results up to 10 kHz. In other words, you have to engineer this circuit a little to know where it gives valid data. You can't avoid ...

Power supply rejection ratio (PSRR) is an important parameter for many electronic systems because it measures system performance, enabling designers to verify a system meets required performance ...

The principle is simple — if you want to measure how much PSU noise any of your electronic devices let through, known as PSRR (Power Supply Rejection Ratio), you can induce PSU noise with this ...
