Member Function Documentation

setup()

setup	(		self,
		float	readout_frequency,
		float	adc_sampling_interval,
		int	num_adc_samples
	)

Generates the properly formatted frequency word information for the demodulator.

Parameters

[in]	readout_frequency	Rate at which the the ADC data is captured for demodulator calculation.
[in]	adc_sampling_interval	Current ADC sampling interval.
[in]	num_adc_samples	Number of ADC samples used for demodulator calculations.

Returns

None

Member Data Documentation

frequency_word

frequency_word

Object holding binary representation of angle step in half-pi steps.

id

id

Unique ID for demodulator block.

num_cycles

num_cycles

Number of FPGA clock cycles required to process the ADC samples during demodulation calculations.
Currently the ADC is 8x faster than FPGA. Hence every FPGA clock cycle, 8 ADC samples is available.
