Optical Encoder Controls Range Switch - 10/08/98 EDN-Design Ideas:
Several circuits included, scroll to find this one. Instead of using a
counter-controlled, pushbutton-activated range switch, you can use an
optical encoder. Inexpensive encoders are available, and they occupy
minimal space on the front panel of an instrument....(circuit) |

RF Transmitter uses AMI encoding - 11/24/99 EDN-Design
Ideas:.....(design idea) Although alternate-mark-inversion (AMI)
encoding is well-suited for direct-conversion FM transmission, designers
often overlook the technique. AMI, a three-phase, synchronous-encoding
technique, uses bipolar pulses to represent logic ones and no signal
to... |

Rotary Encoder Mates with Digital Potentiometer - 02/06/03 EDN-Design
Ideas: In developing electronic systems, designers look for products or
ideas that may benefit from the better performance, smaller size, lower
cost, and improved reliability that an IC can offer. Toward that end,
the digital potentiometer emerged as an alternative to its mechanical
counterpart, the mechanical potentiometer.....(design idea) |

Stereo Encoder/ Multiplexer - based on NJM2035, very simple circuit
and well documented (circuit) |
|
Veronica Stereo Encoder - As you probably know, to enable
stereophonic broadcasting, audio channels LEFT and RIGHT have to be
specifically encoded in such a way that FM receivers can reconstruct
stereo. This is a low cost, but powerful, stereo coder. Since the
schematic is very 'clean' there's no full documentation available. Just
note that : * Trimmers adjust 19KHz pilot tone and output levels (see
schematics). * Cap. trimmer fine tune the 19KHz pilot tone frequency
(from 76KHz crystal). ….(electronic schematic) |

Encoder & PC Make Complete Motor Control System - 12/12/02 EDN-Design
Ideas: This Design Idea combines a simple ISA-bus-resident interface
circuit; a garden-variety PC; a high-resolution optical shaft encoder;
and a PWM-controlled, 0.05-hp, brushed, permanent-magnet dc motor to
make a high-precision and high-power motion-control system. The system
sequences the precise rotation of an evacuated steel bell
jar.....(design idea) |

KEELOQ® Manchester Encoding Receive Routines - Microchip Application
Note Published 11-May-01 (app note) |
|
NJM2035 Stereo Encoder/ Multiplexer - This stereo encoder is the
perfect solution for those looking for a high quality stereo sound
transmission at a low cost. This stereo encoder produces an excellent
crystal clear stereo sound and very good channel separation that can
match with many more expensive stereo encoders that are available on the
market. It is all possible thanks to a 38KHz quartz crystal that
controls the 19kHz pilot tone, so you will never have to calibrate or
re-adjust the circuit. ….(design) |

NTE789 Stereo Decoder - The NTE789, a monolithic silicon integrated
circuit, is a stereo multiplex decoder intended for FM multiplex
systems. This stereo multiplex decoder requires only one low–inductance
tuning coil (requires only one adjustment for complete alignment),
provides automatic stereo switching, energizes a stereo indicator lamp,
and operates from a wide range of voltage supplies. ….(design) |
