Carpal Tunnel Syndrome Symptoms & Signs. Carpal tunnel syndrome arises from compression of the median nerve that supplies the hand. Symptoms begin with numbness and/or tingling of the hand in the distribution of this nerve (the thumb, index, middle, and thumb side of the ring fingers).
An Condenser microphone is a type of microphone that consists of a pair of charged plates that can be forced closer or further apart by variations in pressure. In effect, the plates act like a sound-sensitive capacitor.
Condenser microphones come with a specification to the amount of voltage needed for power. Check the datasheet of the condenser microphone in use to see what bias power to provide the microphone. Also the datasheet will tell you what value resistor to tie the voltage to. Below is an example of a condenser microphone receiving voltage and its attached resistor.
