Hello,
I have been trying to simulate two speed signals with the following specification. I have tried other labview forums but this particular one has been very helpful to me.Signal 1:
Maximum amplitude: 5V
Minimum amplitude: 12V
Form: Sinusoidal
OP Impedance: ~100 Ohm
Switchable: 8Hz or 800Hz
Signal 2:
Maximum amplitude: 5V
Minimum amplitude: 12V
Form: Sinusoidal
OP Impedance: ~100 Ohm
Adjustable over: 8Hz to 1000Hz
Soft switchable sweep: 800 Hz rising @ 7% per second
800 Hz rising @ 9% per second
800Hz rising @ 11% per second.
I have implemented the first part. For the second one, I have used the formula for the sweep, taking the 7% per second as an example.
From v = u + at where v is freqency, and then integrating:
800Hz to 1.07*800: 800 + 56t
856 Hz to 1.07*856; 856 + 59.2t
915.92Hz to 980.0344; 915.92 + 980.0344t
sin((800* t) + ((56*t*t)/2))+sin((856* t) + ((59.2*t*t)/2))+sin((915.92* t) + ((980.0344*t*t)/2))
I have tried simulating two portions of this sine wave. But I cannot implement the whole thing on a single waveform.Please help. I have attached the Vis for 1 and a trial for the second one.
Thanks.

Hi maxidivine,
Thank you for using the National Instruments forum. I have noticed you have published the same question multiple times. Please use one forum thread. For this, can we keep everything within the forum - http://forums.ni.com/ni/board/message?board.id=170&message.id=421097
Kind regards,

Thank you very much for the clarification and advice.
I am grateful.
