so suppose i have a single-pole (first-order) low-pass RC filter that gives me a unity gain upto the corner frequency of 1536Hz and i apply a 12V amplitude sinewave to the input of the filter and i am getting a sinewave with the amplitude of 4.1V from the output of the filter

Discuss how would i calculate the approximate frequency of the sinewave? see parameters below in the UK Electrical Forum area at ElectriciansForums.net
You have the amplitudes so you can calculate the attenuation. You need an equation for the gain of a first order filter in terms of signal frequency and corner frequency, then rearrange it for signal frequency...
But see my comment in your latest thread!
