AnalogX Frequency Converter allows you to easily convert between frequencies and notes, which can then be used to help target specific areas in a mix. This software also outputs 'cents' based from A0 (27.5hz), for EQ's that do not use named frequencies, and supports fractional notes +/- 50 cents..

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 generated 20 bits and each bit is 6 units long and then it is XORed with another pseudorandom data bits and then it is BPSK modulated and hence two peaks in its FFT are displayed. CDMA programme is infact self descriptive.

- Binary Frequency Shift Keying
- License: Freeware

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 on two frequencies. I hope this will help out students and instructors alike..

- Joint Frequency and Delay Correlation
- License: Freeware

[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 sampling rate. A: vector representing received signal sampled at FS = 2pi B: vector representing correlation code sampled at FS = 2pi FRANGE: Two element vector from lowest to highest frequency to search over within a frequency range from -pi to pi. For Example [-pi/10 pi/10]. Omitting FRANGE will default to [-pi pi]. FDOUT: 2D Correlation surface vs delay and frequency offset FREQ_AXIS: Frequency values aligned to frequency axis (-pi to pi) With no output arguments FDCORR will plot the surface correlation magnitude vs frequency and delay offset in the current figure window.

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 utilized independantly,and this block runs well with the block square function.If i utilize secundly this block appear error dimension after integrator,and we konow that simulink accepts 2 port outputs.For animation i decide to publish now One File per 2 weeks for HEARTVI1(electrical part of heart) and for the global heart with frequency and blood pressure.

- Frequency Of Exercise
- License: Freeware

Frequency of Exercise is the first component of successful cardiovascular exercise work out plans. You should exercise at least three days a week. Those who are very out of shape and/or who are overweight and doing weight-bearing cardiovascular exercise such as an aerobics class or jogging, might want to have at least 36 to 48 hours of rest between workouts to prevent an injury and to promote adequate bone and joint stress recovery. Duration of Exercise is the second component and refers to the time you've spent exercising. The cardio work out plan, not including the warm-up and cool-down, should vary from 20-60 minutes to gain significant cardiorespiratory work out plans and fat burning benefits.
