The Journal of the Acoustical Society of America, 1964 A new speech compressor is described. We have named this device the bandpass compressor (BPC) because it is based on the idea that the output of a narrow-band filter can be adequately described by means of two slowly varying parameters, the amplitude envelope, and the instantaneous frequency.

Glomerular Barrier Behaves As an Atomically Precise Bandpass Filter in a Sub-nanometer Regime
Nature Nanotechnology, 2017 The glomerular filtration barrier is known as a “size cut-off” slit to retain nanoparticles or proteins larger than 6~8 nm in the body, and to rapidly excrete the smaller ones through the kidneys.

Optically reconfigurable microstrip UWB bandpass filters [PDF]
, 2010 This paper presents an optically reconfigurable microstrip ultra-wideband filter. A single optical switch comprised of a silicon wafer is activated using near infra-red light to select between either a bandpass or bandstop response.

Novel folded SRR-loaded waveguide bandpass filters [PDF]
, 2008 A novel class of E-Plane, low-cost, compact and metamaterial-based filter structure using FSRRs for microwave, millimeter wave applications has been proposed. The proposed FSRR-loaded waveguide bandpass filter has been designed and simulated at 9.45 GHz.

An efficient algorithm for downconverting multiple bandpass signals using bandpass sampling [PDF]
ICC 2001. IEEE International Conference on Communications. Conference Record (Cat. No.01CH37240), 2002 Bandpass sampling is a useful alternative for direct digital downconversion in software radio. It significantly relaxes the analog-to-digital converter (ADC) sampling rate requirement and facilitates the design goal of moving the ADC as close as possible to the antenna.

Improved Designs for Highly Integrated Lowpass–Bandpass Filters
IEEE Access, 2023 This study presents three dual-band lowpass–bandpass filters. The first handles lowpass and bandpass bands through its fifth-order and third-order Chebyshev filter responses, respectively.

Terahertz frequency bandpass filters [PDF]
Journal of Applied Physics, 2007 The design, measurement, and analysis of a range of artificial materials for use at terahertz frequencies are described. The chosen structures consist of arrays of cylindrical gold-plated pillars with period comparable to the wavelength of incident radiation.
