Software Downloads for "Pure Sine Wave Inverter"

Hello, Can anyone help me debug my "Single Phase Inverter" model? I have it semi-made, i have pwm features in there, but i just can't get it to work. I need to achieve a Pure Sine Wave, at the output. And also at variable frequencies. I have a transformer attached at the output too, to achieve multiple ranges of voltage outputs. One of the main problems i am having is, that in the signal builder, i have tried to make a 'Triangular Wave', in order to achieve a PWM, but i think a faulty 'Triangular Wave', is causing me problems.

This model simulates a quasi square wave inverter developed using two cascaded square wave inverter..

The model simulates the single phase square wave inverter.

A single phase motor is is operated using a quasi square wave inverter with third harmonic cancellation. A dead band of 60 degree has eliminated almost all the third harmonic component..

Ericsynth is a lightweight application written using the Java programming language that allows you to generate and play a sine wave.

The usage is simple: just select the desired audio frequency, set the oscillation lifetime and press the 'Play' button to generate the sound.

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.

Cosinor analysis uses the least squares method to fit a sine wave to a time series. Cosinor analysis is often used in the analysis of biologic time series that demonstrate predictible rhythms. This method can be used with an unequally spaced time series. Follows cosinor analysis of a time series as outlined by Nelson et al. "Methods for Cosinor-Rhythmometry" Chronobiologica. 1979. Please consult reference. Input: t - time series y - value of series at time t w - cycle length, defined by user based on prior knowledge of time series alpha - type I error used for cofidence interval calculations.

A simple sine wave synthesizer with 128-note polyphony. Made to make funny little bloopy sounds, the pitch envelope is the important part (well, and the cool anti-aliased ADSR widgets
;).

A sine wave is used to modulate the speed at which the input signal is playback.
Does exactly what it says on the tin. Basically, a sine wave is used to modulate the speed at which the input signal is played back at (i.e. stretching and squashing the audio). To do this, a buffer is employed, which also allows the input audio to be output in reverse, hence the direction button which can be seen above. This is another plugin which probably doesn't have too many practical uses, but I quite like the sounds it makes.

Biorhythm is an attempt to predict various aspects of a person's life through simple mathematical cycles.
These cycles begin at birth and oscillate in a steady sine wave fashion throughout life.
Most biorhythm models use three cycles: a 23-day "physical" cycle, a 28-day "emotional" cycle, and a 33-day "intellectual" cycle.

Biorhythmix lets you chart your biorhythm for any day. You can also chart the biorhythms of any person.

Features:
- People list;
- Show a user's Physical, Emotional and Intellectual rhythms in values and curved graphs;
- Composite graph;
- The ability to touch and hold the plot area to trigger the popup window with the values of cycles;
- Compute compatibility between people;
- Go to date;
- Live tiles;

ToneExtractor can decode DTMF (dual-tone, multi-frequency) signals back to numbers

The following are the frequencies used for the DTMF system, which is also referred to as tone dialling. The signal is encoded as a pair of sinusoidal (sine wave) tones which are mixed with each other. DTMF is used by most PSTN (public switched telephone networks) systems for number dialling, and is also used for voice-response systems such as telephone banking and sometimes over private radio networks to provide signalling and transferring of small amounts of data.

subhuman is a specialized 2 Osc synth for creating powerful sub bass, either for low down basslines, or sub-bass kick drums and drops. subhuman has been updated to add a pitch envelope, contoured graphical envelopes, note-on sync, waveform display and oscillator phase. It also now has a Pure sine oscillator for Osc1, which is generated by real-time math to avoid interpolation and give a pure Signal

By playing notes several octaves below Middle C, subhuman will Create a deep sub bass from the pure sine wave generated by Osc1.

Instead of Triangular wave generator from Library browser Embedded Matlab func (user defined) is used. Make sure that tha amplitude of sine and triangle wave are equal.and also the freq of triangular is not less than twice the freq of sine wave.(remember sampling theorem?) And to increase the simulation speed decrease the sampling time value in unit delay block..

Visualize wave propagation through media with different impedances and propagation velocities. Wave Propagation is a natural phenomenon that is important in many physical systems. Text books leave much to be desired regarding visualization of wave propagation since they are not animated. The package has a sequence of 6 models that have both a transient pulse excitation as well as a sine wave excitation. The model sequence starts with a one transmission line version that has user definable source and load impedance and evolves to a three line model using an exponentially tapered matching section.
