A multiple-feedback path bandpass/bandreject filter which exhibits a nearly constant Q over a predetermined frequency range, and which is tunable by means of a single variable impedance element is provided. A Thevenin equivalent voltage source is placed in series with the tuning element, wherein ...

A simple realisation scheme for OTA-C universal biquadratic filter A simple scheme for realising four standard second-order voltage transfer functions, viz., low-pass, highpass, bandpass, and band-elimination is presented. It is implemented by using only operational transconductance amplifiers and cap...

FDMA systems have higher cell site system costs compared to TDMA systems because of the need to use costly bandpass filters to eliminate spurious radiation at the base station. • The FDMA mobile unit uses duplexers since both the transmitter and receiver operate at the same time. A duplexer...

I have a 20 cm PCB log periodic with a preamp/bandpass filter that I normally feed into my permanent ADS-B decoder( RTL-SDR and RPi3). On the Portapack I would normally run with both gains at 40 and the amp off. I have tested the new code with >50 aircraft detectable and quite ...

Every channel's crossover consists of a high pass filter (HPF) and a low pass filter (LPF), along with the frequencies and filter types used. Each output's crossover section is essentially a bandpass filter, making it necessary for the user to map out ahead of time which outputs will ...
For each auditory region, the bandpass-filtered MEG source-space data were Hilbert-transformed to derive the instantaneous phase for each time and grid point (for an analysis overview, see Fig. 1A). We quantified the state of oscillatory activity in 46 frontal, central, and parietal ROIs. ...
