Device for correction of the passband of an air gap transformer with a cut-off frequency, characterized in that it includes a filter adapted to be connected to the transformer in series, and in that the filter is adapted to amplify the signal that it receives from the transformer for ...
1 deal with interface 108 and the functional blocks that set the carrier frequency. For example, a radio-frequency reflectometer can be constructed by replacing speaker 130 and microphone 140 in interface 108 by an RF antenna or an RF-signal coupler, and utilizing an RF carrier frequency in ...
the frequency responses with various values ofs1ands2are plotted in Figure11. Accordingly, the passband bandwidth off1can be adjusted by tunings1, while the passband bandwidth off2could be changed by tunings2. Thus, the passband bandwidths off1andf2could be independently controlled by changing the...

As the passband of the digital filter narrows and the low- and high-frequency components of the spectrum are cut off, the wave front of the recorded pulse becomes more gently sloping, resulting in an increase in the difference of arrival times (DAT) of pulses to the AE transducers and in...
Two high-pass frequency responses with different cut-off frequencies are realized. Since the two converted intensity-modulated signals are out of phase, the overlapped frequency responses are cancelled, and a single-passband filter is realized. The bandwidth and the central frequency can be tuned ...

In accomplishing this, the circuit impedance changes from a value fH/fL times the normal design filter characteristic impedance Ro to a circuit impedance value with a cutoff frequency reduced to fL. BEN H * TONGUE
