AI Thread Summary
Programs like SPICE can analyze circuits using z, y, s, and abcd parameters, with the .NET statement in SPICE being particularly useful for these calculations. Users can verify their manual calculations by utilizing software tools designed for circuit analysis. LTSPICE is recommended as a reliable SPICE application for this purpose. The discussion emphasizes the importance of confirming parameter values in microwave circuit analysis. Overall, leveraging software can enhance accuracy and efficiency in circuit parameter determination.

Hey all,

Is there some sort of program that allows one to analyze circuits in terms of z, y, s, and abcd paramaters? A lot of my microwave course revolves around analysis in this fashion, and I want to ensure that I am determining the correct paramaters for a given set up.

As an example, in the image we have a transistor with a resistor. The transistor (alone) has the impedance matrix shown in the image. Is there a program that can tell me the z, y, s, abcd parameters of the circuit as an entirety? I can do it by hand, but I'd like to check my answers.

Thanks in advance,

sandy

Yes, the .NET statement in SPICE will compute all of that. I confess I have never used the .NET statement...
If you need a SPICE app, google "LTSPICE".
 

Thread 'Underwater piezoelectric sensor array receive sensitivity'

Hi all I have some confusion about piezoelectrical sensors combination. If i have three acoustic piezoelectrical sensors (with same receive sensitivity in dB ref V/1uPa) placed at specific distance, these sensors receive acoustic signal from a sound source placed at far field distance (Plane Wave) and from broadside. I receive output of these sensors through individual preamplifiers, add them through hardware like summer circuit adder or in software after digitization and in this way got an...

Thread 'Following up on the recent thread about Earth Resistance measurements'

I have recently moved into a new (rather ancient) house and had a few trips of my Residual Current breaker. I dug out my old Socket tester which tell me the three pins are correct. But then the Red warning light tells me my socket(s) fail the loop test. I never had this before but my last house had an overhead supply with no Earth from the company. The tester said "get this checked" and the man said the (high but not ridiculous) earth resistance was acceptable. I stuck a new copper earth...

Thread 'Question about bonding ground and neutral'

I am not an electrical engineering student, but a lowly apprentice electrician. I learn both on the job and also take classes for my apprenticeship. I recently wired my first transformer and I understand that the neutral and ground are bonded together in the transformer or in the service. What I don't understand is, if the neutral is a current carrying conductor, which is then bonded to the ground conductor, why does current only flow back to its source and not on the ground path...
