Calculates the frequency of characters within a block of text. In the context of cryptography, these values can be compared to a frequency table in order to attempt to ascertain the original message.
From time to time one needs to calculate the average frequency of concurrently running processes/threads. This class just does this.
Provides a widget for Content Taxonomy module similar to Taxonomy Tree with one major difference - it only loads term tree branches required instead of rendering the entire taxonomy tree on page load.
At the moment it has been tested to...
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...
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...
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...
It is a new block library simulink called Detection of Frequency of periodic signal.
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...
[FDOUT, FREQ_AXIS] = FDCORR(A,B,FRANGE) FDCORR Joint frequency and delay correlation Performs an efficient circular cross correlation between two vectors over all possible frequency offsets (Dopplers) between -pi and pi where 2pi is the...
THIS FUNCTION PLOTS FFT OF THE SIGNAL INPUT TO THE FUNCTION IS
userfft(input, sampling frequency, waveform, psd)
input -> Input waveform
sampling frequency -> Sampling frequency

After publishing my new block library simulink Detector of Frequency Signal,I calibrate for having linearity,so in input F=1HZ out is F=1HZ.
This m-file plots the transmitted signal of slow frequency hopped spread spectrum.This uses one symbol transmission per frequency hop.
This code optimises the parameters for the term structure of volatility (TSOV) applied to historical forward curves - see discussion in Harris in reference 1 below.
TSOVs avaible are: TermType - 1 = sigma = A exp (-CT) - 2...
It is the HEARTVI1FP1 block simulink of global functionnement of the heart with frequency and blood pressure.Training this block you will see that can happen a problem.One subsystem is the detection of frequency signal,and this block run well if...
adding a 2nd order filter we can plot variation in frequency due to the faults or disturbances.
Frequency-to-note converter that uses equal temperament system. - Returns difference as cents if frequency is out of tune.
The script uses only one transmission symbol per frequency hop.
Provides a term blacklist for freetagging vocabulary.
Use this module to force all content submitted by a user to be associated with a term from a taxonomy.
#D7CX: I pledge that Forced Term will have a full Drupal 7 release on the day that Drupal 7 is released.
