A. A Doppler-radar based intrusion detection system ("a burglar alarm") is measuring a single sinusoidal voltage that varies between -15 and +15 V. And the frequency is between 5 and 100 Hz. The measured waveform is displayed on a screen for supervision purposes. Match the ExternalInterface Requirements (EIR) for this particular input (see Section 5.1.2 of the textbook) with a coherent description. The answers might contain additional specifications to illustrate the necessary data for your requirements. EIR Description 1. Name of the item 2. Description of purpose The A/D-converted samples are 16-bit unsigned integers; -15.1 V = 0000 (hex), O V = 7FFF (hex), +15.1 V = FFFF (hex); 1 bit corresponds to 0.46 mV 3. Source of input Measures Doppler waveforms for supervision purposes 4. Valid range 5. Accuracy The measurement accuracy must be better than +/- 10 mV The maximum voltage from the intrusion detector is +15 V and the minimum -15 V; to avoid saturation, the voltage range shall be- 15.1 V... +15.1 V 6. Units of measure 7. Timing The buffered Doppler output of a radar- based intrusion detector None The sampling period is 0.25 ms, its punctuality is better than +/-0.01 ms 8. Relationships to other inputs 9. Relationship to outputs Volts 10. Data format Measured samples shall be available as outputs for the screen driver no more than 0.1 ms after each sampling moment doppler input
