We describe phase response as "minimum phase", "linear phase", etc. Is there a name for a phase response in which the group delay is everywhere nonnegative? Thanks, Greg

Hi, Can someone pleas help me find the folowing article: "Analog to Digital Conversion of Voice by 2,400 Bit/second Mixed Excitation Linear Prediction (MELP)," Federal Information Processing Standards Publication (FIPS PUB) Draft, June 12, 1997 I?me just a poor student not able to pay 35$ for an article. Thank you Karel Bruneel

Hi, I have downloaded a melp1200 c code from the internet and am trying to port it adsp-2188. There is an array declared in qnt12_cb, by the name of res256x64x64x64 which has a size of 0x2300. The maximum segment which I can define is of 8k. I am using overlays. Is there a way to fit this array into the memory without decomposing it??? Other wise I will have to make segments of this array and k...

Hi, I am looking for MELP test vectors to verify my implementation. Can someone point me in the right direction? I expected they would be easy to find - considering the DDVPC have 3 publically available MELP implementations - but I can not find test vectors anywhere. Regards, Nick

Hello, I sent a request to get MELPe through s5066.nc3a.nato.int two months ago, but I did not receive a reply. Is there another way to the MELPe with 600 bps. Could someone in the USA share the updated MELPe code with me? Please sent the code to kathyz@torreypinestechnologies.com or mail the code to Kathy Zhang Torraypines Technologies Inc. 12396 World Trade Drive Suite 117 San...

For secure portable device that is based on 533MHz Power PC processor or Pentium, we would like to use low rate vocoder. We realized that MELP or MELPe vocoder may be best for rates between 600 and 2400 bps. Do we need DSP or can we use simpler and cheaper solution such as the Power PC/Pentium processor itself? If we need to use DSP implementation, which DSP/implementation be the best? ...

In a FHSS system like Bluetooth, how is synchronization to the hopping sequence done? For example, for a specific hop sequence, is a special code sent at the beginning of a frame on the initial hop channel by the FHSS "master" and all slaves listen in and synchronise? Is short-term stabilty assumed good enough that synchronization can be mantained through all channels in the hopping seque...

Hi, I know RS code has a 't' parameter, but I don't know the last one in RS(544, 514, T=15, M=10). Can you tell me that? Thanks,
