lower half-power frequency
1Half power point — The half power point of an electronic amplifier stage is that frequency at which the output power has dropped to half of its mid band level. This occurs when the output voltage has dropped by 3 dB and the power has dropped by half. A bandpass… …
2Power supply — For the Budgie album, see Power Supply (album). A vacuum tube rackmount adjustable power supply, capable of +/ 1500 volts DC, 0 to 100mA output, with amperage limiting capability. A power supply is a device that supplies electrical energy …
3Frequency — For other uses, see Frequency (disambiguation). Three cyclically flashing lights, from lowest frequency (top) to highest frequency (bottom). f is the frequency in hertz (Hz), meaning the number of cycles per second. T is the period in seconds (s) …

7Frequency comb — A frequency comb is the graphic representation of the spectrum of a mode locked laser. An octave spanning comb can be used for mapping radio frequencies into the optical frequency range or it can be used to steer a piezoelectric mirror within a… …
8Frequency divider — A frequency divider, also called a clock divider or scaler or prescaler, is a circuit that takes an input signal of a frequency, fin, and generates an output signal of a frequency: where n is an integer. Phase locked loop frequency synthesizers… …
