Balancing the
Wheatstone Bridge
An understanding of how values of unknown resistances can
be discovered using a variable resistance and a Wheatstone Bridge |
|
Bridge amplifier
bridge amplifier measurement, In the
(normal) case of a large open-loop gain of the opamp (typically >100 dB) the
feedback mechanism will force the opamp input voltage difference to be virtually
zero. In this limit the amplification factor of the circuit will be determined
solely by the resistance values |

Maxwell-Wien bridge unlike this straight Wien bridge, the balance of the
Maxwell-Wien bridge is independent of source freq |

Superheterodyne spectrum analyzer
a spectrum analyzer
is an extremely useful measurement tool that can show, in the frequency domain,
information not readily recognizable with a time domain instrument such as an
oscilloscope. For example, the frequency content of a signal (e.g. a fundamental
sinusoid and one or more harmonic components) is readily identified with a
spectrum analyzer |

Cathode Ray Tube
This applet traces the path of an electron through the steering plates of a
cathode ray tube. The path of the electron and the image on the display are both
shown. The final deflection of the electron from the axis is calculated and
given |

Lissajous figures
What are Lissajous figures, Lissajous applet, Lissajous figures were used to
determine the frequencies of sounds or radio signals. A signal of known
frequency was applied to the horizontal axis of an oscilloscope, and the signal
to be measured was applied to the vertical axis. The resulting pattern was a
function of the ratio of the two frequencies |
