Power Supply | Power supply definition goes here. |

Common Mode Voltage | Common Mode Voltage definition goes here. |

Input Signal Level | Input Signal Level definition goes here. |

Gain | Gain definition goes here. |

Fo | Center frequncy for bandpass filter.s |

Fc | Cutoff frequency for highpass and lowpass filters. |

Q | "Quality factor" of the filter. Q is directly related to peaking in the individual sections. |

Resistance | The impedance at DC. |

Reactance | The impedance at frequencies other than DC. |

α | The damping ratio. Which is the inverse of Q (1/Q) (the quality factor Q). |

Filter Type | This describes the transfer function of the filter: Lowpass, highpass or bandpass |

Highpass | Passes frequencies above the cutoff, atenuates those below. |

Lowpass | Passes frequencies below the cutoff, atenuates those above. |

Bandpass | Passes frequencies around the center frequency, attenuates those on either side. |

Filter Response | This describes the transfer function of the filter as it relates to amplitude and phase response. Standard responses that we support are Bessel, Butterworth, Chebyshev (0.01 dB to 1 dB), Equiripple (0.05° & 0.5°), Gaussian (6 dB & 12 dB). |

Filter Order | Describes the attenuation rate. Each degree in the order provide 6 dB/octave (or 20 dB/decade) attenuation and 180° phase shift. |

Filter Topology | Decribes the actual circuit schematic. |

H | Filter gain (can also be called A). |

A | Filter gain (can also be called H). |

S | This is =jω. Filters are often described by the response in the s plane. The degree of s is the order of the filter. |

ω | The frequency in radians/sec. = 1/2π the frequency in Hertz. |

Hertz | The frequency in cycles/sec. |

Amax | The maximum ripple in the amplitude of the filter in the passband. |

Amin | The minimum attenuation in the stopband. |

Fmax | [Fmax info goes here] |

Fs | The edge of the stopband. |

Passband | The band in which the signal remains unattenuated. |

Stopband | The band beyond Fs. This is the band where the response of the filter never exceedes the minimum attenuation (Amin). |

Transition band | The band between the [passband and the stopband. |

Transfer function | The frequency response of a function or circuit. Usually given in terms of s. |
