These circuits were found in the February 1995 issue of Electronics Now magazine. The circuits have normal response in (a), boost in (b), cut in (c), and plate response in (d).
This circuit converts signals from the 350 kHz to 500 kHz longwave (VLF) band to the 4.35 to 4.6...
The oscillator shown in the figure can generate signals between 3 and 15 MHz approximately, depending...
We found this circuit in an old documentation. The instrument can be an ordinary multimeter in the...
