UnitDelay
Delays a signal by delay_length samples.
Processing
- Samples are stored in a buffer of delay_length; each new input outputs the sample received delay_length samples earlier.
- The output carries the timestamp of the sample just received (the value is the one received delay_length samples earlier).
- For the first delay_length samples, zeros of the same length as the input are output.
Usage
- Typical inputs:
data_vectorizer.o_data→input. - Typical outputs:
output→GeoDistance.target_geoPoint.
Data format
- One input/output pair of the type selected by data_type is created; vectors are supported.
- The vector length may change from sample to sample, up to the buffer size of the first sample; a delayed sample keeps its own length.
- delay_length must be 1 or more.
