Five sections of the spectrum display circuit

Posted on Mar 28, 2007

Is the use of LM324 as a band-pass filter, LB1405 for five-band spectrum display drive display circuit. Point 3 is selected frequency harmonic relationship, their center frequency is 100Hz, 330Hz, lkHz, 3.3kHz, 10kHzo band-pass filter is 0 = IO.KF = o 20 cases

of design calculations using the display driver LB1405, since the display fewer bands, display input of the driver is provided with an input sensitivity adjustment potentiometer, so have not been accurately calculated.
