Webinar Video Questions & Answers Q: For the voice scrambler, were patents available that could be reverse engineered? A: Two very important branches in voice communication were and are CELP and MELP. Type inside Google "CELP compression patents" and be astonished that these developments are still going on this day. One of the older patents can be found too. Have a look at this link for more information, just as an example: http://www.google.com/patents/US5742930 Note that Philips Usfa in t ...
Webinar Video Q&A Q: What would be required to make it a polyphonic synthesizer? What are the limitations (bottlenecks) in the current design for making this possible? A: A polyphonic design would probably require a much more optimized sound engine. The limitations are as always the MCU speed and available memory. Q: I never have heard the term "bitcrusher" could please say a little bit more about it? A: A bit crusher is an effect that reduces the number of bits used to encode samples. For ...
Webinar Video Q: Is this project summarized in a single Elektor magazine? A: Yes, in the December 2014 edition. Q: Can I buy the kits/built boards via Element 14? A: No, they are sold by Elektor (www.elektor.com) Q: Which controller is being used, please? A: LPC812M101JDH20FP (TSSOP20) Q: is the rotary encoder optical? A: No, it has sliding contacts. Q: 16K bits or bytes of flash? A: 16 KB i.e. bytes Q: Hi Clemens! Does the mcu can provides PWM outputs to drive a full bridge for motor control? ...
Webinar Video Q&A Q: What do you think about a separate Power-Supply-Board instead of integrated Power-Supply in each Board? I did consider this as a possibility, but felt that the real benefit of the T-Board was that it was simple and self-contained.  I felt that the added complexity of a separate power supply board would not result in any cost-savings, and would just make the board a little less easy to use. Q: How much current can the T-board provide the external circuitry? The T-Bo ...

View the Webinar Video Q: What output noise level could one hope to achieve? Is this limited by the AD chip or by other components? The ADAU1701 datasheet specifies the A-weighted S/N noise at 104dB. This is therefore the best you can achieve and is limited by the AD chip. Q: What is the maximum stop band attenuation achievable? The stopband attenuation characteristics of a filter is determined primarily by the transfer function (e.g. Butterworth, Bessel etc) and not so much by the hardware impl ...
View the Webinar Video Q: Sample and Hold doesn't seem to be mentioned much nowdays - is this because of the much faster conversion rate of modern A/D converters? Have you any advice on when to use S/H? Thanks Gerry Yes, as you point out S/H is not mentioned much nowadays. This is because the A/D converters are much faster and also nowadays most A/D converters have built-in S/H circuits. You can however purchase S/H units if you think your signal is varying fast and your A/D converter is slow. Q ...
We’re excited to announce that the Freescale Technology Forum Americas is coming in April 2014! And because the event has grown so much over the years, we’ll be at a truly “Texas-sized” venue in Dallas.
