Hello friends who helps me and please explain what this means in this diagram?

No diagram was uploaded, please try again in order not to have to guess, usually in a scheme the resistors are indexed and displayed with R1, R2, Rx ... and capacitors with C1, C2, Cx. where X represents a number to differentiate them from each other ..

The link is on foot, basically it is a way of indicating the values to be used for that specific circuit according to the bandwidth to be managed by the amplifier, this can be seen on page 7 (seven). The parameter, "B", is the frequency response of [-3dB].

They have already responded and I took the boldness and so that the message makes more sense without having to go anywhere, upload the photo of the scheme that concerns us. Regards. Ric.

If one did the calculations for these low passes whose combination is quite complex and considering the 15 [Khz] to (-3 [dB]), it gives us about 47 [nf] and not 39, well the design engineering rules, I just wanted add this.

The X is used as an incognite indicator and a value will be assigned depending on an equation, in this case of the profit that you want to achieve that is indicated in the scheme itself with the equation RX = 20 * R2. The same applies to the capacitor CX = 1 (2pi B * R1). These components are part of the feedback loop and determine the operating income.

What value would then be for a good profit of the oprrscional?

There are no good or bad profits. Everything will depend on what we intend to do. Of the maximum distortion we are willing to tolerate. of the level of the input signal, of the application that we give to the circuit.
