Hello,

I am trying to run the General Real FIR-Filter Block between the ADC and DAC - Block.
Somehow it doesn't work. There is a Data-Typ problem.

Does anybody has an example how to deal with the General Real FIR-Filter (Target for TI C6000)

Thanks a lot.

Which ADC/DAC blocks? What are the data types coming out of the ADC and
going into DAC. Turn-on signal 'Port data type' display to
see what is going on with data types. Post more details about the error
message, your model etc.

The ADC and DAC belong to the C6416 DSK. I use the Output(ADC) Data type: double.

For the "general real fir-filter"-block I need to convert the data type: double to Q.15.

How can I do that?

I got it!

Used the "data type conversion" block. Its working fine.

Do you have an idea how I can create a hilbert-filter with blocks in the package C64xDSP Library?

Are there any pdfs with examples for the Target TI C6000?

I'd like to know how I can use the "matrix multiply"-block, etc.

I have another question regarding the "general fir-filter"-block belonging to the TI
C64xx - package.
The design of a Filter (e.g. LPF) depents on the H - parameter. Is there an easy way
to get the H-parameter for a desired filter?
