Tables Ease Microcontroller Programming - 04/22/10 EDN Design Idea When creating microcontroller firmware, you often need to work
with data arrays. Tables make easy work of data arrays, such as those for digital-code transformation,
correction for sensor linearity, sophisticated calc. . . [by Abel Raynus, Armatron International, Malden, MA]
Tachometer Avoids Analog Vices - 11/10/94 EDN Design Idea 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 t. . . [by Tan Van Nguyen, IBM SSD Division, San

Tack a log taper onto a digital potentiometer - 01/20/00 EDN Design Idea It's sometimes convenient to have digital control of the volume
level in an audio system. The use of multiplying DACs (MDACs) is problematic because of the switching noise
of the ladder network. This noise comes from the bit swi. . . [by Hank Zumbahlen, Analog Devices, Campbell,
