Rolled-Off Noise Source - This is a circuit that generates white
noise, rolled-off to drive earphones or a small speaker. White noise creates
is a "rushing" sound, which sounds something like air rushing by your ear(s).
White noise would be flat with frequency,(circuit added 6/07) |

Simple fix adds door-chime repeater - 05/13/99 EDN-Design
Ideas....Electromechanical door chimes can enhance your home, but they are
vulnerable to costly repair problems. A defective pushbutton switch or a
careless visitor can maintain the chime in an energized state for a
prolonged period, thereby damaging the chime. The....PDF contains many

Software PLL locks VCXO to reference - 08/03/98 EDN-Design Ideas....The
circuit in Figure 1 provides a precisely controlled clock signal. The method modifies
the controller's quartz oscillator such that the control voltage at point P1 controls
the frequency. A D/A converter using an R-2R ladder network connected to output port D
generates the control voltage. A precise reference-frequency signal....Multiple

Unlocked PLL Retains Locked Frequency - 07/20/95 EDN-Design Ideas....Using
the PC2 in-phase comparator output, the circuit in Fig 1 keeps the unlocked, or
free-run, frequency of a 74HC4046 PLL near the locked frequency. With no signal input,
the VCO output normally adjusts to its lowest frequency (one-half the locked
frequency, f0]. In some applications, such.... [Design Idea by Karol Freed, HAC,

Veronica 1W PLL FM Transmitter - The VERONICA transmitter is a very stable,
powerful, and high quality FM emitter. Thanks to a PLL, the output frequency is
controlled with DIP switches. Output power is approximatively 1W with a single
regulated 13.8v supply ! (see specifications) Features : * High RF output power : 1W *
Full 87.5-108MHz range (100KHz increment). * Very stable output frequency : Crystal
reference & Phase Locked Loop. * Professional input bandwith (fully RDS compatible ) *
No complex tuning needed. * High quality PCB * Full documentation & construction
details available.….(Circuit design added 12/08) |

Wireless PLL Stereo FM TX with LCD - Now you can use your MP3 Player to
listen your favorite tunes through any FM stereo receiver. Wireless FM transmitter
wirelessly connects portable music players to your car or home stereo quickly and
easily. Just plug the FM Transmitter into the headphone jack of your MP3 or any audio
source including iPOD, PDA, CD Player, Cassette player or connect it to your PC or
laptop computer. Tune your card stereo or receiver to the clearest FM frequency, and
enjoy your digital music with full sound and convenience. |
