VIDEO LOW PASS FILTER DESIGN TABLE
By: Don McClatchie Video low pass filters are useful to reduce noise for analog video signals and as anti-aliasing for analog to digital equipment designs. When used in analog noise reduction designs the cut-off frequency is set just above the highest useful frequency in the

GUIDE TO MAXIMUM CABLE LENGTHS
GUIDE TO MAXIMUM CABLE LENGTHS These cable distance maximums are industry preferences and longer lengths can be used. The use of cable signal boosters can greatly extend the usable cable lengths. Also the cable quality will have a major impact on maximum cable limitations. FORMAT
ELECTROMAGNETIC RELAY DEFINITIONS
ELECTROMAGNETIC RELAY DEFINITIONS By: Don McClatchie When designing or repairing electronic circuits that use electromagnetic relays a clear understanding of the important operational parameters of the relay can help you build a better project or help you to determine the reason for a failure. Let’s start with
IP CODE “INTERNATIONAL PROTECTION RATING”
INTERNATIONAL PROTECTION RATING "IP CODE" IP CODE FIRST DIGIT (SOLIDS) SECOND DIGIT (LIQUIDS) IP00 NOT PROTECTED FROM SOLIDS NOT PROTECTED FROM LIQUIDS IP01 NOT PROTECTED FROM SOLIDS PROTECTED FROM CONDENSATION IP02 NOT PROTECTED FROM SOLIDS PROTECTED FROM WATER SPRAY LESS THAN 15 DEGREES FROM VERTICAL IP03 NOT PROTECTED FROM SOLIDS PROTECTED FROM WATER SPRAY LESS THAN 0 DEGREES FROM VERTICAL IP04 NOT
WHEN LED’S ACT LIKE PHOTOCELLS
WHEN LED'S ACT LIKE PHOTOCELLS By: Don McClatchie Just about everyone that has played around with electronics knows about the LED (Light Emitting Diode) and everyone can see them in our electronic devices to indicate the condition of things. I remember experimenting
FDNR FILTER DESIGN FORMULAS
FDNR FILTER DESIGN FORMULAS By: Frank McClatchie The following formulas can be used to convert a normalized low pass filter design to a FDNR configuration that converts two normalized series inductance and one shunt normalized capacitance through the FDNR conversion process to resistors that simulate the same
IDENTIFYING CURB MARKINGS OR GLYPHS
IDENTIFYING CURB MARKING OR GLYPHS The next time you are out walking on the street, have a look at the sidewalk curbs. You will notice some cryptic markings either painted on the curb or carved into the curb like a Glyph or sometimes markings the on
