Pi Filter has Sharp Notch - Simple filter network makes a
great low-pass filter having a sharp notch just outside passband. Can
be implemented as active filter using GIC circuit. Use this component
calculator to determine resistor and capacitor values. Voted best of
issue!.... [Jim Haggerman, Hagerman Technology LLC] |

Pi Section Coupler - Inexpensive gadget tunes antenna for
better DX. Almost any receiver covering 540 kHz to 1600 kHz is
suitable for broadcast band DX'ing, and there are a lot of them. But
the antenna is another matter. If you are new to the hobby, or if you
have been having trouble DX'ing those really difficult stations, you
may find the answer to your reception problems in a properly
constructed long-wire antenna - and the "Pi-section Coupler".... [by

Soft-limiter circuit forms basis of simple AM modulator - 3-Sep-07 Issue of EDN
Inserting diodes biased by reference voltages in the feedback loop of an op amp yields a
soft limiter that you can use as the basis of an AM modulator.... [Design Idea by Herminio
Martínez, Encarna García, and Juan Gámiz, Technical University of Catalonia, Barcelona,
Spain] |
