sine wave modulation

[alertvinay]

I am in need of a LV program which goes this way....

A sine wave is to be generated of fixed frequency which in the first half cycle starts from zero amplitude and increases exponentially for 12ms, becomes stable with constant amplitude of 5v for about 40ms, decreases to zero in the next 12ms....in the next half cycle, it should be zero for 64ms(12+40+12) and the cycle should repeat continously...
I have an arb waveform generator((5421 card)..


also if possible, I need a front panel where i can change the exponential inc/dec time, the time for which the signal maintains const amplitude and also the half cycle durations....

plz help..
Thanks in advance

Hello Vinay,

You can find attached vi to generate a waveform similar to what you want.

You can modify the code to fulfill you requirement.

Hardik

Kudos are always welcome 🙂

Hello,

In LV 12 student I am using MT niFgen AM-SSB Signal Generation vi. I need some way to replace the pilot tone and use an analog signal from my sound card to modulate the message sine wave with a microphone or .wav file any advice?
