A full-aperture energy rejection filter
is recommended for use with Schmidt-Cassegrain or Maksutov telescopes.
The reason for the decline is the stronger rejection filter
that prevents suspicious returns from being processed.
This paper aims to explore the total effect of the bandpass filter (BPF) and rejection filter
(RF) on the ECG signal recorded by a high-resolution electrocardiograph based on nanoelectrodes without filters in the band from 0 to 150 Hz .
The nonlinear characteristics of diodes generate unwanted harmonic signals that propagate backward to the antenna and forward to the load; therefore, a harmonic rejection filter
, a DC-pass filter, and a matching circuit for the diode impedance should be carefully designed to obtain an optimized [[eta].sub.RF-DC] [7-11].
The network functions as a harmonic rejection filter
and dc feed inductors in the class E amplifier.
The Raman microprobe incorporates a Rayleigh scattering rejection filter
, CCD-TV camera for sample positioning/monitoring, and white light illumination.
These devices integrate a current amplifier, a 50 Hz/60 Hz rejection filter
to eliminate artificial light flicker and a 15-bit ADC (analog-to-digital converter).
The output of the differential CMOS LNA is connected to a balun and passes through an image rejection filter
to the single-ended mixer.
We investigated various parameters for potential rejection filters
. The criteria used to select the filters are that a valid and efficient rejection filter
should not generate any false negatives and should be able to significantly reduce the number of chemicals for experimental evaluation.
