Sensor llustration 7 Chapter 13 Digital signal Processing Systems 17) It is important to be aware of the range and accuracy limitations of actuators and sensors. Therefore it is important to carefully consider their input and output A) voltage limits B) power requirements C) heat dissipation D) signal specifications Sensors 14) Conceptually, a sensor is a component with a single output as in Illustration 7. A sensor outputs a signal that varies over time. When dealing with signals that represent physical phenomena, we can think of a sensor as a device that converts energy from one form (heat, light, pressure, etc.) to another form (typically an electrical voltage). Which following parameters are important with sensors? 18) What are important parameters when selecting an ADC for an embedded system? 1- Range 2- Quantization 1- Range 2- Resolution 3- Sample Rate 3-Signal quality 4- S/N ratio A) 1,2,3 B) only 1 C) 1 and 3 D) 2,3 A) 2.4 B) 1,3 C) 1,2,3,4 D) 3,4 19) If a low amplitude signal is linked directly to the ADC, it is unlikely to make a good use of ADC capabilities, essentially under utilizing 15) In Ilustration 7, which is most representative our ADC. An electrical engineer might use the of RAW signals that are obtained from sensors? A) B B) A C) A&B D) Neither term signal under-loading to describe this design flaw. This design flaw does what A) use too few ADC bits for resolution B) overrides ADC operation C) causes sign inversion with overflow D) not enough range for low impedance input 16) Much like a sensor, conceptually, an actuator 20) In Illustration 8 what letter points to the is a component with a single input. Often times, an actuator will convert its analog or digital input signal to some form of energy Actuators can have which response? A) Binary - On/Off B) Linear C) Pulse width Modulated D) All of the above clipping limit of the ADC input? B) A ?) ? D) C
