Basic block diagram of audio spectrum analyzer 2. Operation theory: Input signal comes into each filters. Filters are band pass filters. They only pass signals belonged to fixed frequency range and remove others. We can use transistor and discrete capacitors and resistors to make active filters or we can use OP-AMP and other passive device.
