Methods and apparatus to position a mobile receiver using downlink signals part IV
TL;DR: In this paper, the authors present methods and apparatus to estimate the position and velocity of a Mobile Receiver (MR) using either the time of arrival (TOA) of signals received by the MR, their Phase Of Arrival (POA), their SOA, or a combination thereof, with respect to a reference produced by a Reference Receiver (RR) of known location.

Switched capacitor filter utilizing a differential input and output circuit
TL;DR: An integrated circuit for filtering signals by having cascaded switched capacitor sampling filters is described in this paper. But it does not specify the number of filters that need to be sampled at a lower rate to inhibit anti-aliasing.

A.E. Atia,A.E. Williams +1 more
TL;DR: In this paper, a procedure was described whereby narrow-band pass waveguide filters having ripple in both the passbands and stopbands can be synthesized in the form of coupled waveguide cavities.
Patent
Audio signal peak energy equalization
TL;DR: A phase-distorting network is used in a carrier wave transmission system to delay to different extents the different component frequencies of an unsymmetrical audio signal from a source 20 without substantially affecting the intelligibility of the signal as discussed by the authors.
