Setup Tests Bit Error Rate - 03/18/04 EDN-Design Ideas....Traditionally, the
reception quality of a digital receiver is expressed in terms of BER (bit-error rate].
This figure is the proportion of received bit errors in a given period. Typically, you
measure the BER in the lab by applying an RF signal, modulated by a pseudorandom code,
to the receiver under test....EDN is migrating links. This link is not verified.

Signal Controls Sine Generator - 05/15/03 EDN-Design Ideas....The circuit of
Figure 1 produces an accurate, variable-frequency sine wave for use as a
general-purpose reference signal. It includes an eighth-order elliptic,
switched-capacitor lowpass filter, IC3, which uses a 100-kHz square-wave clock signal
that microcontroller IC2 generates. (Any other convenient square-wave source is also
acceptable....[Design Idea by Simon Bramble, Maxim Integrated Products, UK] |

Simple µC acts as dedicated motor-control - 09/11/98 EDN-Design Ideas
Motion-control systems often use a PWM signal to control the duty cycle for a motor
driver or amplifier module. Typical designs generate the PWM signals using �Cs with
dedicated PWM output lines, such as the PIC16C65 (Microchip Technology,
www.microchip.com) and the HC11 (Motorola Inc....File contains several circuits,
