How to Design a Series Resonant Circuit with a Bandwidth of 500Hz?

AI Thread Summary
To design a series resonant circuit with a bandwidth of 500Hz using a 120V constant supply and a 50nF capacitor, additional information about resistance or inductance is necessary. The discussion highlights that without knowing the resistance or inductance, it is challenging to achieve the desired bandwidth. The user notes that the circuit could be modified for a bandwidth of 200Hz, but still lacks critical parameters for the original design. The consensus is that essential details are missing, making the task difficult. A complete circuit design cannot be established without these specifications.

Hi Guys,

I usually don't come on forums to ask for any issues but i am stuck.

I have been given these details:
  1. A 120v Constant supply at all Frequencies
  2. 50nF capacitor
With these components i am supposed to design a series resonant circuit which will achieve a bandwidth of 500Hz. 500Hz is the significant value i have been told to look at.

I have been looking through the formulas for RLC Series and i cannot seem to find a way of produce a circuit with those details.

Am i missing something or is it possible to do?

Thanks

It looks as if some item of information is missing. Is there mention of the resistance or anything else?
 
Hi tech,

thanks for the reply. The only other information is it can be easily modified to 200Hz and that is all.

To me this seems the case that there is information missing since in a series resonant circuit you need either and L or R to get started working back through the bandwidth where as the parallel you can utilise the capacitor.

Thanks q
 
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...
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 'Beauty of old electrical and measuring things, etc.'
Even as a kid, I saw beauty in old devices. That made me want to understand how they worked. I had lots of old things that I keep and now reviving. Old things need to work to see the beauty. Here's what I've done so far. Two views of the gadgets shelves and my small work space: Here's a close up look at the meters, gauges and other measuring things: This is what I think of as surface-mount electrical components and wiring. The components are very old and shows how...
