Digital Signals produce Pure Sine Waves - 10/09/97 EDN-Design
Ideas.....Analog oscillators produce excellent sine waves but are temperamental and
hard to design. They also require extensive redesign every time you change the
oscillation frequency. Digital oscillators…. EDN

Digital sync-tip clamping: a new approach to video-signal conditioning -
10/08/98 EDN-Design Idea In digital sync-tip clamping, a stand-alone "clamping"
ADC (CADC] incorporates the dc-restore function at its input and eliminates the need
for external timing strobes. This technique encompasses a complete front-end
architecture, including sync detection and automatic gain control (AGC] and
provides..... [Design Idea by Lazar Shifrin, Advanced Imaging Solutions] |

Digital Tachometer Avoids Analog Vices - 11/10/94 EDN-Design Ideas.....The
digital tachometer in Fig 1a is a component of the digital seek servo loop in Fig 1b.
The loop produces an error signal that causes a motor to follow a sophisticated
velocity profile (Fig 2]. Although you could use an analog tachometer, the digital one
costs less, performs better, is less sensitive to temperature, and implements easier
in a custom IC..... [Design Idea by Tan Van Nguyen, IBM SSD Division, San Jose, CA] |

Digital Thermostat with LED Temperature Display - I needed to replace two
old, unreliable thermostats for controlling the heating and cooling for a large garden
shed. Commercial basic digital thermostats are available quite cheaply, but some lack
the ability to control heavy loads or have the extra features that I require for
saving energy when the door is often left open or to indicate temperature being out of
range etc. I like the PIC18F1320 microcontroller used in my previous project, so
decided to use it again in a very similar design to drive three multiplexed LED
displays and read the temperature from a Dallas/Maxim DS18x20 "1-Wire" digital sensor.
