|
Three Band Equalizer - (schematic / circuit design added 9/02) |
|
Three Level Audio Power Indicator - Battery-operated3 LED display that connect it
to loudspeaker output (added 04/02) |
|
Three-band, Active Tone Control - Provides Bass, Midrange and Treble boost and
cut. Single-supply operation. (circuit design added 9/06) |
|
Tone Control (Aaron Cake) - This simple tone control can be used in may audio
applications. It can be added to amplifers, used as a stand alone control module, or
even built into new and exciting instruments. It's one IC construction makes it a very
compact circuit, as only a few support components are required. Plus, it does not use
a dual power supply.... designed by Aaron Cake (electronic circuit added 04/05) |
|
Tone Control (Andy Collinson) - Based on the classic Baxendall tone control
circuit, this provides a maximum cut and boost of around 10dB at 10K and 50Hz. As the
controls are passive, the last transistor provides a slight boost. The output….(added
9/02) |
|
Tone Controls with 2x Ne 5532 - check also PCB design and notes (added 4/02) |
|
Tone detect with the NE567 T - one detection circuit with the NE567 (electronic
design added 08/08/08) |
|
Tone Detector - (electronic circuit added 7/03) |
|
Tone Generation - Microchip Application Note Published 26-Aug-97 (app note
added 2/06) |
|
Tone Generator - (electronic circuit added 7/03) |
|
Two Tone Generator - This two-tone generator includes 3 ICs NE555 Astable
Multivibrators. You can vary the duration of each tone by changing the 10k resistor or
100MF capacitor at IC1 or changing resistors and capacitors at IC1/2 for higher or
lower tone. Designed by Andrew R. Morris (added 6/06) |
Voltage Clamp circuits for ultra-low-voltage apps - Today's electronic systems
often ... made to simulate a low-power Zener shunt regulator, using two parallel- ....
The precise, ultra-low gate threshold voltage is used to control the sharp, fast ...
r ....(circuit / schematic added 09/08) |

|
Voltage Controlled Panner - This circuit is used to convert a mono audio signal
into a stereo signal that can be panned between the left and right channel by a 0-10V
control signal, it is intended for analog synthesizer systems….(electronic design
added 6/07) |
|
Volume Control - Circuit of a digital volume control using six discrete ICs,
including a 5V regulator, is presented. IC1 (555) is configured to function as astable
flip-flop. Its frequency or period may be adjusted by proper choice of resistors R44,
R45 and capacitor C6 combination. Here it is for 0.3 second period.….(circuit design
added 08/08) |
|
Volume Control (Aaron Cake) - based on DS1669 Digital Pot IC (added 8/03) |
|
Volume Control (Rod Elliott) - A volume control using a linear pot that is much
better than most log pots (added 4/02) |
|
Volume Control has Log Taper - 04/11/02 EDN-Design Ideas: potentiometers provide a
compact and convenient way to attenuate audio-amplifier signals. However, most such
potentiometers suffer from at least one flaw: a nonlogarithmic step increment. To
avoid this problem, a user must usually step the potentiometer in a nonlinear sequence
to simulate a logarithmic taper.....(design idea added 12/04) |
|
Volume unit meter spans 60 dB dynamic range - 11/10/05 EDN-Design Ideas:
Comparator monitors difference between input amplitude and peak-detected
output.....(design idea added 10/06) |
