Detailed Description

template<class SampleType>
class FFTChannelInternal< SampleType >

FFT channel.

FFT Unit. Takes a time domain real signal as its input and outputs frequency domain data in real/imaginary format.

Each input channel generates two output channels. The even number channel is the real data and the odd numbered channel contains the imaginary data. (The IFFTUnit expects the data in this format.)

Factory functions:

• ar (input)

Inputs:

• input: (unit, multi) the input unit FFTs a signal. FFT channel.

Member Typedef Documentation

template<class SampleType >

typedef ChannelInternalCore::Data FFTChannelInternal< SampleType >::Data

To store channel state data.

Sublasses should inherit from this, add their own members, and store an instance. Where applicable the structure should match the equivalents in the Plink library.

Reimplemented from ChannelInternalCore.

Member Function Documentation

template<class SampleType >

void FFTChannelInternal< SampleType >::initChannel

(

const int

channel

)

throw () [inline, virtual]

Called to initialise the channel's initial value.

The ChannelInternal subclass should initialise itself using this channel of its inputs, calling initValue().

Implements ChannelInternalCore.

template<class SampleType >

void FFTChannelInternal< SampleType >::process	(	ProcessInfo &	info,
		const int	channel
	)		throw () [inline, virtual]

The DSP function.

This function will do all the processing for derived class.

Implements ChannelInternalCore.
