Multitone Generator (labview)

[martinmistere]

Non so se è la sezione giusta...

Non riesco a capire come funziona questo blocchetto...o meglio non riesco a settare i parametri in maniera esatta... sad.gif

I miei dubbi sono nel settaggio del tone phasis, tone amplitude e tone frequences!

Come faccio a settare questi parametri in modo da generare un onda sinusoidale con 3 componenti armoniche (la 1a ad esempio a 10kHz, la 2a a 5kHz e la 3a 1kHz)?

qualcuno me lo progetta e me lo spiega?plz...se qualcuno non mi aiuta mi impicco con i cavi del pc! sad.gif sad.gif

Il blocchetto ha i seguenti collegamenti...

amplitude is the value that the sum of all the tones is scaled to and is the largest absolute value that the waveform contains. The default is –1. amplitude is useful when outputting the waveform to an analog output channel. If the maximum value that the hardware can output is 5 volts, set amplitude to 5. If amplitude 0, the scaling is not applied.

tone frequencies is an array in which each element is a single tone frequency. The size of this array must match the size of the tone amplitudes array and the size of the tone phases array.

tone amplitudes is an array in which each element is a single tone amplitude. The size of this array must match the size of the tone frequencies array and the size of the tone phases array.

tone phases is an array in which each element is a single tone phase in degrees. The size of this array must match the size of the tone frequencies array and the size of the tone amplitude array.

sampling info contains sampling information:

Fs is the sampling rate in samples per second. The default is 1000.

#s is the number of samples in the waveform. The default is 1000.
