This paper is concerned with design of cascading CIC filter and FIR filter to improve the passband droop and stopband attenuation for decimation filter. Decimation filter has wide application in both analog and digital systems for data rate conversion as well as filtering. We have three class of filters FIR, IIR and CIC filters. IIR filters are simpler in structure, but not satisfy linear phase...

Obtaining labels can be costly and time-consuming. Active learning allows a learning algorithm to intelligently query samples to be labeled for a more efficient learning. Fisher information ratio (FIR) has been used as an objective for selecting queries. However, little is known about the theory behind the use of FIR for active learning. There is a gap between the underlying theory and the moti...

A finite impulse response (FIR) equalizer is practically employed in conjunction with the Viterbi detector for data detection process in magnetic recording channels. However, the FIR equalizer with a large number of taps is required at high density storage channels. It is well-known that an infinite impulse response (IIR) filter with a small number of taps can closely approximate such an FIR fi...

Multiple Constant Multiplications (MCM) are widely used for implementing transpose form pipelined Finite Impulse Response (FIR) filters. In biomedical applications like Electro Cardio Gram (ECG) the coefficients of FIR filters remain fixed. In these applications, Full flexibility of a multiplier is not necessary. Once the MCM method is implemented, it can be called as many times if needed. Tran...

BACKGROUND The objective of this study was to evaluate the interaction between the length polymorphism of the guanosine thymidine repeat [(GT)n] in the heme oxygenase-1 (HO-1) gene and far-infrared (FIR) therapy on access flow (Qa) and arteriovenous fistula (AVF) patency in hemodialysis (HD) patients. METHODS A total of 280 HD patients were randomized into a control group (n = 141) and the FI...

In this paper, we propose a serial equalizer for doubly-selective channels. We use a Basis Expansion Model (BEM) Finite Impulse Response (FIR) to model the doubly-selective channel and to design the serial equalizer. In contrast to our previous works, we decrease the modeling error of the BEM FIR by fitting the BEM FIR to the true doubly-selective channel over a time-window that is independent ...

In this paper, baclqlane channel characteristics are f i s t analyzed. It is round that channel group delay distortion is also n major IS1 contributor in addition to amplitude attenuation. AMATLAB program is then described for optimization of FIR filter under LMS ...

Detailed far-infrared (FIR) and mid-infrared (MIR) studies of aluminum small particles have been carried out. MIR absorption studies of clustered and non-clustered samples suggest that the anomalous FIR absorption does not arise from the clustering together of the individual metallic particles. The MIR absorption, which is too small to be the continuation of the anomalous FIR absorption, could ...

The large group delay of the high order FIR filters is unacceptable in some applications. So, recently, how to reduce the group delay of FIR filters has been studied intensively. To reduce the ringing in the time domain and to maximize the stopband attenuation, it is useful to design FIR filters with maximally flat characteristics in the passband and transmission zeros in the stopband. We prese...

In this paper, we propose a new nonlinear filtering algorithm that can provide more accurate and reliable localization compared with the pure particle filtering (PF). In the proposed algorithm, failures of the PF are detected, and the failed PF is recovered using a finite impulse response (FIR) filter. The resulting filter is called the combined particle/FIR filter (CPFF). We demonstrate the pe...
