Simple Biasing Circuit
I'd like to formally understand this simple biasing circuit:
Let V+ be the supply voltage, Vi be the input voltage at the seemingly unconnected terminal of the capacitor, and let Vo be the output voltage at the junction between the resistors and…

MAX9924 input signal and bias?
I'm trying figure out how to connect a MAX9924 ("Variable-Reluctance Sensor Interface with Differential Input and Adaptive Peak Threshold") to a sensor on a rowing machine. My knowledge of electronics is about the battery and light bulb level. The…

0.5v bias on a clock pin?
To verify that I've soldered a pin correctly, I took a scope capture and noticed there is a ~560mV high bias. This is on an old motherboard where one or more capacitors could be bad. What is a good way to bring this clock signal into a digital…

D/C Decoupling Capacitor for Microphone Bias
I have the circuit below which provides a bias voltage to a microphone:
C10 is listed as a 47uF (bipolar) capacitor
Is there any reason I can't use something like a 100nF bipolar ceramic instead?

(Frequnecy of) Bias tees and looking for online retails
Currently, I'm looking for some bias tees to add some DC bias to RF signals (whose carrier frequency is not determined yet, but definitely lower than 30 MHz and amplitdue does not exceed +/- 3 V.)
Since I'm not familiar with electrical engineering,…
