  • The element is used in implementation of low-pass ladder filters.
  • The transformed ladder filter realizes the DC transfer gain as the ratio of two capacitors.
  • The leapfrog filter maintains the low component sensitivity of the passive ladder filter that it simulates.
  • The design starts out with a known ladder filter of one of the typologies shown in the previous figure.
  • Very high quality IF filters, called crystal ladder filters, can be constructed by using serial arrays of crystals.
  • Usually, all the elements of the ladder filter are lossless except the first and the last which are lossy.
  • The signal flow-graph representation of the ladder filter equations with impedances scaled by R, an arbitrary resistance.
  • A "'leapfrog filter "'is a type of active circuit electronic filter that simulates a passive electronic ladder filter.
  • During the 1930s, as techniques in network analysis and synthesis became better developed, designing ladder filters by image methods became less popular.
  • A lattice delay section has twice the delay of a comparable ladder filter section, and this helps to mitigate concerns over component duplication.
  • The arrangement of feedback loops in the signal flow-graph of the simulated ladder filter inspired the name " leapfrog filter ".
  • It is possible with this circuit to have the characteristic impedance specified independently of its transmission properties, a feature not available to ladder filter structures.
  • Using a four element voltage input, voltage output ladder filter } } as an example, the equations that relate the element voltages and currents are as follows:
  • Generic ladder filters with either ( a ) voltage input / voltage output, ( b ) current input / voltage output, ( c ) voltage input / current output or ( d ) current input / current output.
  • The lapse of patents in recent years, such as for the Moog synthesizer transistor ladder filter, has spurred a return of DIY and kit synthesizer modules, as well as an increase in the number of commercial companies selling analog modules.
  • The envelope settings, like all of the voice settings, are selected by the voice ROMs . The 24 dB / oct low-pass filter, ARP part no . 4034, was very similar to the Moog ladder filter, and was eventually replaced due to a patent infringement claim by Moog.
