This function file is basically for Passive Butterworth Filter for Low pass as well as for High Pass. In input it takes the Pass Band Attenuation, Band Stop attenuation, Band Pass Frequency, band stop frequency, and Filter Type. For Low Pass Type is "0" and for High Pass Type is "1". It finally output the values of Inductors and Capacitors..

- Acceleration Filter
- License: Freeware

Explore the effects of low-pass filters on acceleration sensors!
Discover how low-pass filters work on acceleration sensors by viewing the outputs in real-time. Acceleration Filter runs multiple low-pass filters at once so you can compare the results from a single input quickly and easily. The output from the filters is plotted with a line graph while the noise is plotted with a bar graph. There is also the option to view the acceleration as a two-dimensional vector. The user can select the sample period in units of seconds to apply to the different filters.

Intelligent Wifi Client
Android based service to Intelligently switch between the different Wifi and Mobile Networks
STEPS DONE
1 Interfacing with Accelerometer sensor to get the raw readings.
2 Applying the high pass and low pass filter to the RAW readings. High pass will acceleration due to gravity =9.8. Low pass will give the external acceleration. We need the external
acceleration to detect if we are travelling.
3 Interfacing with GPS to get the latitude and longitude.
4 Getting the WIfi Connection available from Android Wifi Manager.

This is a work in progress and there's no presets yet, sine wave is missing (I like to use this to add extra bass to the low end so it will be added for the next version) unlike my other synth Minaton this doesn't rely on libsamplerate and instead uses minblep bandlimited waveforms for each of the three oscillators, at the moment saw, square (with pulsewidth) and noise are supported. Three LFOs with tempo locked speed and two envelopes one for filter, one for filter. Low pass resonance filter also can be set for notch or high pass, oscillators have sync, updates to come soon.

TranceGate is kind of like a tremolo on steroids, you'll notice a collection of vertical bars at the top of the screenshot. These bars represent volume levels, so if you imagine the signal travelling from Left to Right, as it hits a bar, the volume level of that bar is applied to it. If the bar is all the way at the top, the volume level is full, likewise all the way down it is off. There are also tempo in BPM, and Note duration. BPM is set by the host DAW, and if there is no DAW, then it is set to 120.

function [g] = FFTPF1D (X,binsize, f, P) Discrete Fourier Transform Low/High Pass Filter. % This is a simply implement of such a filter for a given 1-D data. X: the array of you data, each data point is a bin of signal binsize: the bin size in your data data f: the cutoff of wave length, P: 1, or 0, true or false : true, low pass, which eliminating higher than f frequence signals, false, high pass, which eliminating lower than f frequence signals. It could be easily modified into 2-D version, or translated into R/S-language.

- Twinny Filter (HLB_ Pass filter) at ISM_ Frequency Band
- License: Freeware

In wireless topology we using filters as main part of system, we proposed a flexible filter for multi-purposes working at ISM band frequency. Obviously the filter idea works by splitting the Band Pass Filter into two types H.P.F & L.P.F controlled by logic circuit to select the desired filter. However the proposed filter can be working as HPF or LPF combines together provide BPF. ISM band [402-405MHz] the unlicensed frequency is selected to work at ISM band for medical applications.

- Real-Time Iris Identification
- License: Freeware

A moving average filter averages a number of input samples and produce a single output sample. This averaging action removes the high frequency components present in the signal. Moving average filters are normally used as low pass filters. In recursive filtering algorithm, previous output samples also are taken for averaging. This is the reason why it's impulse response extends to infinity. We have developed a low computational approach for iris recognition based on 1D moving average filter. Simple averaging is used to reduce the effects of noise and a significative improvement in computational efficiency can be achieved if we perform the calculation of the mean in a recursive fashion.

AlgoTestd-OC?D? is an easy to use testing program for measuring the noise level of soundcards and their Frequency distribution.
It displays the noise parameters like the noise level peak to peak (p-p) and true rms, as well as the DC offset of the input signal. As this measurement is very accurate, even high quality soundcards or external ADCdlDLs (Analog to Digital Converter, e.g. DAT) connected via digital interface to the computer can reliably be tested and compared.
The integrated DC-Filter can be used to remove the influence of DC components present in the input signal.

This is my first music software synthesizer project, developed over the last two weeks it's now in a usable state but there are still things I wan't to do, In using floating point values for all parameters I tried to get away from the steppy digital sounds you often hear on software synthesizers, I've used real analogue synthesizers since the late 1980s so know how they should sound, deep, warm, fluid and rich. The synth has three oscillators, two LFOs, One low pass resonant filter, oscillator sync, two ADSR envelopes which can be redirected to oscillator pitch.
