hello,how can i get a impedance vs frequency graph in Pspice in case of filters?

 

Hi,

Well to start it depends what impedance you want to find, input, output, or other.
The methods vary slightly.
Do you know how to analyze AC circuits using a frequency like w=2*pi*f ?
If so that makes it easier. If not, we have to do some work.

 

Do analyze AC
Parallel input pins connect source current. For example:
Iin pin1 pin2 dc 0 ac 1 .
The voltage on pins will be equal to the input impedance.
Is it Similarly defined output impedance.
I use this method for a long time.

 

Hi,

Oh yes he did mention spice didnt he. LT Spice simulator is free to download.

 

The described method is suitable for any Spice. I used this method 30 years ago, when I was Spice2.

In this bpf how can i get impedance vs frequency graph and power consumption in

Look up Waveform Arithmetic in the Help file.
To get power dissipated in a part, place the cursor over the part while holding down the Alt button.

 

You can do an AC frequency sweep in Pspice.

It took about 8 seconds to Google this up.

 

what are the advantages and applications of increased bandwidth in a band pass filter?

There are no advantages or disadvantages.
It depends upon the frequencies you are trying to suppress versus the signal frequencies of interest.

 

See my example:

 

Bordodynov:
What is in2 in your simulation? Is it ground? Thanks.

 

in2 is just a name. Actually I am not quite right. On the input impedance affects more load. Unfortunately I do not know what the source and the load. It is more correct to connect the first circuit on the output load. The second to the input must be connected (in parallel) of the generator impedance. If this is done, then all will be correct.

 

Thanks. So for the output impedance, you are leaving the input float. I think it will be more exact if we assume the input voltage source is ideal and then short the input voltage for output impedance measurement.
