Circuit Forms Satellite Dish ComMand Decoder - 03/04/04/04 EDN Design Ideas /
(added 1/05) By decoding the commands sent by a direct-broadcast satellite receiver
that uses the DISEQC (digital-satellite-equipment-control) protocol, you can
troubleshoot the commands or simply listen in. Eutelsat Corp (www.eutelsat.com) offers
the DISEQC protocol. The technique uses only the coaxial cable between the receiver
and the dish to send commands for actions such as changing the low-noise-block...... |

Hints and Kinks for USB Decoding - 05/(07/02 EDN Design Ideas / (added 1/05)The
USB is a serial data-transmission system that uses cables to connect peripheral
equipment to PCs. All new computers have two or more USB receptacles, and the
predictions are that they will replace most of the legacy receptacles on older PCs.
The 1.0 and 1.1 standards for USB were for 1.5 and 12 Mbps at lowand full-speed rates,
respectively.... |

LFSR Provides Encryption - 09/13/01 EDN Design Ideas / (added 1/05) LFSRs
(linear-feedback shift registers) find extensive use in cryptography. For example, the
cryptographic algorithms in the GSM (Global System for Mobile communications)
mobile-phone system rely on the use of LFSRs. An LFSR comprises a register containing
a sequence of bits and a feedback function.... |

Manchester Co Decoder Fits into 32 Macrocell PLD - 01/06/00 EDN-Design Ideas /
(added 08/05) -Manchester encoding is common, and this scheme erases the dc-spectrum
component present in an NRZ signal in baseband transmissions. An important application
is in Ethernet-interface adapters, in which several kinds of media-attachment units
interfac... |
|
Microcontroller Visualizes Hex Code - 04/27/00 EDN-Design Ideas / (added 7/03) -In
C systems, information exchanges usually use the hexadecimal 1-2-4-8 format; output
data also appear in this format. Reading the hex code is not a problem; several LEDs
connected to the output lines can display the answer. The problem arises when you w... |
|
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 added 11/08) |
|
PAiA: How MS Stereo Decoder works - The schematic diagram of the MS Decoder may
look complicated but is actually quite simple. Both the Mid and Side signals are
initially …. (circuit design added 07/07/07) |
|
Phototimer Controls Load - 04/18/02 EDN Design Ideas / (added 1/05) In
industrial and home applications, the need sometimes exists for a device that, after
activation by some physical effect, such as light, temperature, or sound, switches a
load on for a predetermined time. The load, such as a lamp, motor, solenoid, or
heater, usually derives its power from the ac line.... |

Professional Stereo Encoder - Uses high quality NJM2035 stereo coder IC.
….(electronic schematic added 11/08) |
|
Remote Control Encoder/Decoder with PIC16C620 and PIC12C513 - (circuit /
schematic design added 6/06) |
|
Rotary Encoder Mates with Digital Potentiometer - 02/06/03 EDN Design Ideas
/ (added 1/05) 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.... |
|
Selective Calling Decoders - This isn't an Electronics Australia/Dick Smith
project, but if you're interested in decoding and logging the selective calling (Selcall)
and Automatic Number Indication (ANI) signals used in mobile radio communications
networks, take a look at the Anzac Comms selcall decoder page. I (Bob Barker) did
the (Zilog) microcontroller software and the PCB layouts for them! |
|
Sequential Channel Selector Simplifies Software - 01/04/01 EDN-Design Ideas /
(added 7/03) -An efficient but powerful circuit is useful for a variety of
applications with limited I/O and for which you want to use one input to
sequentially select a different output channel ( Figure 1 ). When the software
changes the state of only one input,... |
|
Simple Phototimer Controls Load - 04/18/02 EDN Design Ideas / (added 1/05)
In industrial and home applications, the need sometimes exists for a device that,
after activation by some physical effect, such as light, temperature, or sound,
switches a load on for a predetermined time. The load, such as a lamp, motor,
solenoid, or heater, usually derives its power from the ac line.... |

Simple Surround Sound Decoder - This surround-sound decoder is based on the "Hafler"
principle, first discovered by David Hafler sometime in the early 1970s. The
original idea was to connect a pair of speakers as shown in Figure 1, for use as
the rear speakers in the surround setup....(electronic design added 6/07) |

Single Printer Port Pin Acts as an Encoder Output - 06/(07/01 EDN-Design Ideas
/ (added 7/03) -Encoders and decoders are common elements in alarm,
remote-control, and measurement systems. However, most of these devices require
many I/O lines when under microprocessor or PC control. For example, the HT-12E
encoder has eight address pins, four... |
