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.

Global stability, limit cycles and chaotic behaviors of second order interpolative sigma delta modulators [PDF]
, 2011 It is well known that second order lowpass interpolative sigma delta modulators (SDMs) may suffer from instability and limit cycle problems when the magnitudes of the input signals are at large and at intermediate levels, respectively.

Design of microstrip quint‐band lowpass–bandpass filters with flexible passband allocation
IET Microwaves, Antennas & Propagation, 2022 In this paper, newly proposed microstrip quint‐band lowpass–bandpass filters are presented. The lowpass filter structure comprises a meandered transmission line and modified T‐shaped resonators.

Nonlinear behaviors of bandpass sigma delta modulators with stable system matrices [PDF]
, 2005 It has been established that a class of bandpass sigma delta modulators (SDMs) may exhibit state space dynamics which are represented by elliptical or fractal patterns confined within trapezoidal regions when the system matrices are marginally stable. In

A Compact Dual-Wideband Bandpass Filter Based on Open-/Short-Circuited Stubs
IEEE Access, 2020 A dual-wideband bandpass filter is proposed and analyzed, which is based on loaded open-/short-circuited stubs. The dual-band filter consists of a second-order bandpass filter and a third-order bandpass filter, which can be designed separately.
