BH1415 HI FI Stereo Encoder - Latest BH1415 Stereo Encoder design from RHOM
that includes a lot of great features in one small package. It comes with
pre-emphasis, limiter so that the music can be transmitted at the same audio level,
low pass filter that blocks any audio signals above 15KHz to prevent any RF
interference and crystal based stereo encoder for stereo transmission. ….(electronic

Digital Position Encoder Does Away with ADC - 05/08/97 EDN-Design
Ideas.....The position encoder in Figure 1 is a simple yet powerful circuit that
converts the change in resistance of a potentiometer into a digital value without
using an expensive A/D converter. The working principle is a resistance-to-PWM
converter built around the common 555 timer IC. A change in the potentiometer's.....

Encoder and PC make complete motor-control system - 12-Dec-02 Issue of EDN
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 several feet in diameter, such as those used in molecular-beam..... [Design

High-quality Stereo Encoder - This stereo encoder is a halfway between
analogue and digital processing. It combines the best from both domains to provide
high-quality and easy to build device. The sampling frequency used in this stereo
encoder is 97 times…..... |

Improved PL Tone Encoder - A significant amount of interest has been
generated since my last article on a PL tone board. Because of this interest I decided
to improve on the old PL tone design. Figure 1 is an inexpensive PL tone generator
with significantly improved performance. It has a much more stable tone frequency as
well as the elimination of the loading problem on the output. The transistor used in
the old circuit would cause the tone frequency to change at high levels. This
month's circuit eliminates all those problems..... [Radio Amateur Society of Norwich] |

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 added 11/08) |

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
