Build an adjustable high frequency notch filter: 02/06/03
EDN-Design Ideas / Although you can obtain universal,
resistor-programmable switched-capacitor filters that are
configurable as notch filters, most cannot operate at bandwidths
higher than 100 kHz. Further, the typically 16
Composite Amplifier Boosts Precision Of Programmable Voltage
Source : 07/08/02 Electronic Design - Ideas for Design /
Engineers often need dc voltage sources with very high precision
and good resistive and/or capacitive load-driving capability for
industrial applications. However, precision benchtop power
supplies can be very expensive if high accuracy also is...
Wideband Filter Only Has Two Different Components : 01/21/02
Electronic Design - Ideas for Design / Wideband filters with
bandwidths in excess of an octave can be created by cascading a
high-pass filter and a low-pass filter. In this design idea,
nine-pole high-pass and low-pass filters have been constructed
using a modified equal-element design. A...
