Without filter receiving truncated response

Hi

If I don't apply the filter directly receive the transmitted signal after passing through power amplifier then my Amplitude gets truncated, but if I apply the filter then I get to see my full waveform . And also Can anyone tell me how to know the gain of the power amplifier from the waveform received.

Attached is the power amplifier without filter and with filter waveform and the generated signal with and without filter

Hi rashp,

 

Attached is the power amplifier without filter and…

You attached nothing but two blurry images.

No filters, no power amplifiers, no VI!

 

What exactly are you talking about?

 

how to know the gain of the power amplifier from the waveform received.

I guess the answer is found in one of your books for your electronics course…

(In general "gain" is the quotient of output and input.)

 

Best regards,

Express vi for filter was used and FIR filter with 29 taps was used

Hi rashp,

 

as long as you only show images of some plots you will not get much help.

 

Set some default data in your VIs, save the VI and attach it so we can examine it…

Best regards,

Perhaps the two ((near) duplicate) previous posts give more information that just the images (probably not though):

Why not just post a VI?
