The corner frequency of this filter, which has an attenuation of 3 dB at this point, is calculated by the following formula: f3dB = 1/(2π × R × C) where : R is the impedance of the headphones. C is the capacitor value. For a typical headphone impedance of 32 Ω and a 220 ...
R is the impedance of the headphones. (1) For a typical headphone impedance of 16 Ω and a 47 μF capacitor, the corner frequency is 211 Hz. Jack Detection When the JACKDET/MICIN pin is set to the jack detect function, a flag on this pin can be used to mute the line outputs ...
Impedances for all electrodes were kept below 5 kΩ. In Hungary, the EEG was recorded with 32 Ag-AgCl electrodes attached to an elastic electrode cap (Easycap, http://www.easycap.de) using BrainVision amplifier system and BrainVision Recorder software (http://www.brainproducts.com). The ...

amplifier and distort the audio signal: 1) The impedance of the headphone load and the DC- blocking capacitor form a highpass filter with the -3dB point determined by: f−3dB = 1 2πRLCOUT where RL is the impedance of the headphone and COUT is the value of the DC-blocking capacitor...
The MAX32665/MAX32666 are designed with an on-chip matching network providing a 50Ω impedance at the ANT device pin. Filter design must match this impedance for best efficiency. Bootloader Activation The SCPBL is activated following any reset or exiting certain low-power modes if the assigned...
