Resonance Frequency

Frequency analysis allows the calculation of the natural (resonant) frequencies of the design and related forms of vibrations. It is useful in carrying out checks for the resonant frequencies in the working frequency range and optimizing the design in such a way as to prevent the emergence of...

A "ringdown" experiment records the amplitude of a resonator as it decays under the influence of the damping in the system, without any external input. Ringdown.m analyzes a data set from a resonator ringdown measurement and determines the resonator frequency and Q using different methods. An FFT...

AJ Sealed Designer is a sub-woofer design program for solving the required calculations for sealed speaker box designs. AJ Sealed Designer provides accurate theoretical calculations for speaker and box enclosure parameters with an easy-to-use interface. It also includes a box calculator to...

The program is based on no-contact influence on organs and systems of human-being via sound blaster. The principle of treating disease is: the organs have their own unique resonance frequency with which they interact with the outside


Platforms: Windows, Windows CE

Vibrational symphatetic resonance medicine is based on the idea that all illness or disease is characterized by a blockage of the energy channels on some level. When there is a blockage, the organ in question stops vibrating at a healthy frequency and thus it results in some kind of illness. So...

These programmes are not heavily commented but infact are very simple and intutive to understand the Frequency hopping and related tasks.I have made two files for frequency hopping, one of them is not showing 6 proper impulsive peaks but other programme is infact showing them, In DSSS i have...


Platforms: Matlab

Simulink model of a simple Bluetooth wireless data link. Includes error correction, GFSK modulation, frequency hopping and a 100MHz channel.NOTE: A version of this model which works with the current release of MATLAB and Simulink is shipped with the Communications Blockset.


Platforms: Matlab

This script simulates the Binary Frequency Shift keying. Since BFSK is a digital modulation scheme, you can modulate as many bits as you want. however, I have only simulated it for few bits, so that the results are visible.This is code for BFSK only, means it can only modulated two digital states...

It is a new block library simulink called Detection of Frequency of periodic signal.


Platforms: Matlab

This block generates a pulsed signal with assigned amplitude and variable frequency.You must connect the input to sinusoidal signal generator.The block provide convert the sinusoidal signal to quadratic output with amplitude and frequency variable.


Platforms: Matlab

Helps measuring the exact frequency of a signal within a range, by means of finding the maximum of the product of the signal with a sinusoid.Speacially useful when dealing with real-world data.As recently published on my blog: http://loluengo.blogspot.com
