Gain Bandwidth Product: Voltage & dB Gain Explained

AI Thread Summary
Gain Bandwidth Product (GBWP) is calculated using voltage gain (Vo/Vi) multiplied by bandwidth in MHz. It is crucial to note that dB values should not be multiplied or divided; only addition and subtraction are valid operations for dB quantities. The GBWP is expressed in Hz, which means the gain must be unitless (Volt/Volt). Understanding these principles is essential for accurate calculations in electronics. This clarification helps avoid common misconceptions in gain and bandwidth analysis.

If anyone know pls tell me in Gain bandwidth product, gain in what manner (dB or voltage gain (Vo/Vi)) ?
 
Engineering news on Phys.org
It is in voltage gain (Vo/Vi) * bandwidth in MHz.
 
thanks lot
 
Sorry for being intrude, but it is worth while to know that the dB values never should be multiplied or divided. The only allowable operation on dB quantities are addition and subtraction.
Also since the GBWP units is Hz, so the Gain should be unitless (Volt/Volt).
 

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...
