Low-Pass Band-Pass Transformation with Carrier Frequency Drift

Design of Low Frequency Band Pass Filters for SAR applications

Technologies have advanced rapidly in the field of digital signal processing due to advances made in high speed, low cost digital integrated chips. These technologies have further stimulated ever increasing use of signal representation in digital form for purposes of transmission, measurement, control and storage. Design of digital filters especially adaptive or semi adaptive is the necessity o...

High-performance variable band-pass/band-stop state-space digital filters using Gramian-preserving frequency transformation

Processing Power Amplifier Band Pass Filter Band Pass Filter Low Noise Amplifier

—The impact of the type of implementation is considered on the IR-UWB channel capacity. This study is lead for analog and mostly digital implementation. Key parameters and theirs impacts on the channel capacity are exposed in each case: data converters for mostly digital implementations and pulse generators capabilities for analog implementations. These two implementations are compared from a d...

The Band Pass Filter

The `ideal' band pass ̄lter can be used to isolate the component of a time series that lies within a particular band of frequencies. However, applying this ̄lter requires a dataset of in ̄nite length. In practice, some sort of approximation is needed. Using projections, we derive approximations that are optimal when the time series representations underlying the raw data have a unit root, or are...

Dual-Band Band-Pass Filter with Fixed Low Band and Fluidically-Tunable High Band

In this work, we present a dual-band band-pass filter with fixed low-band resonant frequency and tunable high-band resonant frequency. The proposed filter consists of two split-ring resonators (SRRs) with a stub and microfluidic channels. The lower resonant frequency is determined by the length of the SRR alone, whereas the higher resonant frequency is determined by the lengths of the SRR and t...
