22 hours ago · This paper presents a new biquad filter based on carbon nanotube field-effect transistor (CNFET) technology. Implementing various filter modes (high-pass, low-pass, band-pass, and band-stop) in four operating modes (voltage, current, transconductance, and transresistance) with a unified circuit structure is the fundamental feature of the proposed filter. The proposed universal filter is ...
4 days ago · Bandpass filters: These filters can be seen as a combination of longpass and shortpass filters. These filters demonstrate high transmission within a given wavelength range while blocking all...
4 days ago · Optical bandpass filters are typically characterized by their central wavelength, bandwidth, transmission, and blocking. Transmission: The percentage of light, T, that passes through the filter passband. Blocking: Measured as Optical Density (OD), defined as OD = – log10 (T).
5 days ago · The dual-band bandpass-to-bandstop filter exhibits the RF-measured tuning ranges of 1.38-1.53 GHz for the first passband and 1.82-2.08 GHz for the second passband in the bandpass mode operation. The minimum insertion loss varies between 3.3 and 6.8 dB for the first passband, whereas it is between 2.2 and 4.7 dB in the second passband.
2 days ago · This article describes a new family of dual-reject-band filters in rectangular waveguide that uses resonant apertures (RAs), and is suitable for narrow-band applications. Reject-band filters are commonly used to protect from interference in both communication and earth observation systems. The filter structure that we propose is based on a simple modification of the traditional narrow-band ...
2 days ago · A dual-band and a triple-band balun bandpass filters (BPFs) are proposed in this paper, using open-circuited stubs loaded on ring resonators. The proposed baluns are in general composed of three parallel-coupled lines and a ring resonator loaded with open-circuited stubs.
4 days ago · Applies a zero-phase low-pass, high-pass, band-pass, or band-stop filter to the channels selected by picks. l_freq and h_freq are the frequencies below which and above which, respectively, to filter out of the data.
