  • Implement an audio-frequency tilt-equalizer filter
  • Easier: LEFT-CLICK at beginning of copy area. Click to drop anchor. Cursor at end of copy area. SHIFT-LEFT-CLICK. Much easier when highlighting a lot of text. This works in a surprising number of places, like in directories to highlight files...etc.....

  • Two-quadrant multiplying DAC utilizes octal CMOS buffer
  • What's this about? 23 resistors to get a rather poor current-output DAC? And it's only a partial (2V---7V) two-quadrant multiplier? For a few bucks or so you can get real 4-quadrant multplying DACs with a whole lot less manufacturing costs.
