Hi! I was looking thro' the design of the Russian "GO" RLC–2 RCL Meter and noticed this uses a MAX293 "8th Order Elliptic Filter" device to generate the two quadrature sinusoids for the test component, so this set me thinking – can the same approach be used in a D.I.Y. Huntron Design to generate the the 50Hz, 400Hz & 2kHz Component Test Voltage, then fed to a Power …

The MAX293 is easy-to-use, 8th-order, lowpass, elliptic, switched-capacitor filter that can be set up with corner frequencies from 0.1Hz to 25kHz. It is used in this audio spectrum analyzer circuit as an anti-alias filter. The source code and the fixed-point FFT library for ATmega8 are given in the project page.
5KC Active Audio Filter for Brick Wall AM Use
http://amfone.net/Amforum/index.php?topic=22951.0
The point is it's a good idea to be able to switch in an audio filter to limit our AM bandwidth WHEN we crowd up…. and we will sometimes. When the band is clear, we can switch it out and run “full” bandwidth, whatever that means. The idea of operating down in the 3700 area is hi hi FB, but most of the AM stations will not do this.
