The target hardware platform is Stm32f103 - Arm Cortex-M3 based processor.
The functions built in the RadioDSP are:
* Filter BPF CW NARROW (300 HZ)
* Filter BPF CW NARROW (700 Hz)
* Filter LPF SSB ( < 2400 Hz )
* Filter LPF SSB ( < 3500 Hz )
* Noise Reduction (Exponential Moving Average - 3 levels smoothing)
* Noise Reduction (Simple Moving Average - 3 levels smoothing: 8,16,24 samples)
NOTE: this is an experimental project and the functions can be changed
without any advise.
