This paper presents an evolutionary design of digital IIR filters using the genetic algorithm (GA) with modified genetic operators and real-valued encoding. Conventional digital IIR filter design methods involve algebraic transformations of the transfer function of an analog low-pass filter (LPF) that satisfies prescribed filter specifications. Other types of frequency-selective digital filters...

Image editing techniques enable people to modify the content of an image without leaving visual traces and thus may cause serious security risks. Hence detection localization these forgeries become quite necessary challenging. Furthermore, unlike other tasks with extensive data, there is usually a lack annotated forged images for training due annotation difficulties. In this paper, we propose s...

In this paper, a method of realizing voltage-mode (VM) non-inverting high-pass filter (HPF), band-pass (BPF), low-pass (LPF), and inverting (ILPF) transfer functions structure with two grounded capacitors four resistors through an analytical synthesis is presented. The the VM biquadratic consists voltage proportional block lossless integrators based on use current feedback operational amplifier...

Computer-generated graphics are images generated by computer software. The rapid development of computer graphics technologies has made it easier to generate a photorealistic computer graphics, and these graphics are quite difficult to distinguish from natural images by our naked eyes. In this paper, we propose a method based on sensor pattern noise and deep learning to distinguish computer-gen...

In this paper, a modified auto zeroed integrator is used to design and simulate a low-voltage high-Q switched capacitor pseudo 2-path filter.  The filter is a sixth–order Chebyshev band-pass filter operating at sampling frequency of 1MHz and center frequency of 250 kHz with a quality factor of 50. The proposed filter has both low-voltage and high speed properties of the auto zeroed integrators ...

A bank of circuit design solutions for active RC filters the second order is considered - alow-pass filter, a high-pass filter and band-pass filters, in which independent tuning mainparameters pole frequency, quality factor transmission coefficient isprovided. From these positions, requirements three special transfer functions multipolefrequency-setting circuit, contains two resistors capacitor...

In the most common version of an oscillometric blood pressure monitor, the output from the pressure transducer, Y(t), is split into two parts, and used for separate determinations of the pressure inside the pneumatic cuff and its fluctuating part; the latter is derived by sending Y(t) to a high-pass filter (HPF) and amplifying the filtered part to obtain the oscillometric signal O(t). Using a t...

The trans-admittance-mode (TAM) might act as a transforming bridge for voltage-mode to current-mode conversion. In this study a new low voltage operated electronically tunable TAM biquad filter structure realizing all the seven standard filtering functions namely; low-pass (LP), band-pass (BP), high-pass (HP), regular-notch (RN), low-pass-notch (LPN), high-pass-notch (HPN) and all-pass (AP) fro...

Fluorescent lamps introduce a periodic interference signal in optical wireless receivers, which has the potential to severely degrade link performance. Usually, electrical high-pass filtering is employed to mitigate the effects of this interference, but this results in baseline wander or intersymbol interference. Digital pulse interval modulation (DPIM) is a modulation technique which has been ...

The main aim of this paper is to show the utility of cokriging for image fusion (i.e. increasing the spatial resolution of satellite sensor images). It is assumed that co-registered images with different spatial and spectral resolutions of the same scene are available and the task is to generate new remote sensing images at the finer spatial resolution for the spectral bands available only at t...
