433MHz transmitter ATA8402 Application note Has anyone here come across this application note for the ATA8402 (T5754) Atmel 433MHz transmitter? http://www.atmel.com/dyn/resources/prod_documents/doc9115.pdf I have very little RF experience and I might be mistaken, but this AN is very dodgy indeed. I'm trying to make sense of the impedance-matching capa... 22 Jul 2010 05:57

HD tv with standard 4:3 signal Hey Guys, I'm curious about viewing a standard analog 4:3 aspect ratio cable signal on an HD TV. If you visit a TV sales show room they always have an HD signal playing on the TVs. I have a standard cable tv signal to my house I have no plan to upgrade to the upper tier. However, I have one spot where I wo... 23 Jul 2010 23:29

Digital audio line driver I want to drive a digital audio signal over CAT5. I intend to use the DA103 transformer but need to check impedance matching. Will 100R each end of the CAT5 be suitable? Should the 100R on the transmitting end be before, or after, the xformer? -- Dirk http://www.transcendence.me.uk/ - Transcendence UK htt... 2 Aug 2010 19:10

How to set boost converter output voltage ? I have designed with SPICE a simple boost converter with input voltage output voltage ratio of 1:3 - 10.0V goes in and 30.0V comes out. I did this mostly with simple calculations and changing capacitor/ inductor values. Is there a better and more predictable way to do this ? Thanks in advance for your help. ... 21 Jul 2010 19:08
Filter cap at dc motor input I'm rebuilding an old machine for a local company by replacing all the electronics with my own design. It uses a 24V DC brushed motor with an integral reduction gear. The original drive circuit used a couple of SCRs for speed control and current was limited to 3.5A. My circuit uses high frequency PWM (~22kHz). ... 21 Jul 2010 19:08 |
