    measured? 7. Design the basic interface circuit (using an op amp) for a temperature sensor that covers a range of 0° to 70°C if the output of the sensor is 2 mV/1°C and the ADC voltage range is 0 to 4 V. 8. Design an amplifier suitable for converting the output voltage from an LM35 temperature sensor (10 mV/°C) into a signal that makes use of the full input voltage range (0-5V) of the HCS12 ADC port pins. Assume the LM35 is to measure temperatures from 0°C up to +150°C. Show work and circuit! 9. Given a sensor with W that outputs voltage in the range +1.25V to +4.25V. Show the complete interface circuitry needed to connect it to the A/D unit built-in to the HC12 Controller. 10. Write the lines of C code needed to configure the A/D converter, start the conversion, and output a hex integer in the range 0x0000 to 0xFFFF to the variable called data1 that is proportional to airflow input (0.0 to 1.0 litre/min). No further conversion is required ECET 340 Week 4 HomeWork 4 Purchase here Product Description Determine the conversion time for an ADC0804 (8-bit), where 66 clocks per bit are required, if its clock frequency is 50 kHz. 2. If an 8-bit SAR has Vref = 10 V, what is the binary value for an input voltage of 7.28 V? 3. What is the percent error for the binary answer found in Problem #2? 4. Given an 24 MHz bus speed. Write down the line(s) of instruction which set the ATD1 unit for 2MHz…

  • Nt1310 Unit 1 Assignment Analysis

    Pc, to a telephone. I shall run through the process, using Alice (digital Device owner) and Bob (telephone) to describe the process. Before we can begin the call, the pc requires both a microphone and headset/speakers to be able to run any call, and a pc with a fast enough connection to the internet. In this instance, the call will be running as a two way communication known as duplex, which allows the transmission and receiving of information from two connected parties. This means that both…

  • Pipelined Adc Architecture Analysis

    4.1.2 Pipelined ADC The pipelined ADC is one of the most popular ADC architecture. The pipelined ADC architecture is similar to the sub-ranging ADC. The architecture of pipelined ADC is implemented by at least two or more low resolution flash ADCs. The pipelined ADC works from few M samples to more than hundred of M samples with resolution from 8 bit to 16 bits. Due to its high resolution and sampling rate range it is widely used in medical and communication applications like as CCD imaging,…

  • Advantages And Disadvantages Of Modulation

    Frequency modulation is used in a wide variety or radio communications applications from broadcasting to two way radio communications links as well as mobile radio communications. Pulse Code Modulation Mr Alec Reeves introduced Pulse Code Modulation in the year 1937. In this, analog signal is reconstructed to digital signal for ease of transmission by using the analog signal samples. Pulse code modulation (PCM) is a digital representation of an analog signal that takes samples of the amplitude…

  • Importance Of CT Scanner

    The CT scanner Depends upon several steps:- 1-The x-ray tube and detector transverse (scan) the object. 2-The radiation beam passes through the object and is attenuated. The intensity of radiation beam from x- ray tube and transmitted beam both are detected by suitable detectors. 3-The transmitted beam and the references beam are both converted into electric signals. 4-These output current signals are then converted into digital form by analog –to-digital converter. 5-The digital data are…

  • Modem Essay

    technology for them is headed. One of the most common questions that are asked is, what is a modem? Well modem is an acronym for (modulator-demodulator) which essentially means that its primary job is to encode and decode binary signals to allow computers or essentially any end systems to access the Internet. Originally, phone lines were used to carry analog information and a converter was needed to decode these signals, therefore the modem was born. Initially, modems were used as a way for…

  • Raspberry Pi Essay

    microcomputer is based on the Broadcom BCM2835 SoC unit. Generally, the SoC (system - on - the chip) defines the structure that includes a complete microprocessor system, so there is the central unit (CPU), FLASH or ROM, EEPROM and RAM memory, digital and analog devices, and also the analog-to-digital and digital-to-analog converters, as well as serial interfaces. In distinction from the microcontroller, SoC devices are equipped with central units with comparatively large computational power,…

  • Project Analysis: 04.4. Four Mechanical Designs

    The control unit of the project is an embedded system as it is embedded into a small circuit with a microcontroller. The software of the project is developed with the knowledge we gained from the software engineering course. The Arduino programming language used in the project is quite similar to C programming and Java programming. Those courses helped us to write the program for the project. The embedded systems course teaches about Pulse Width modulation, analog to digital conversion, and the…

    have changed quite a lot, whether is be for reasons based on speed - or security. The most common one that is usually referred to as “ethernet cable” today is CAT cabling. The generic blue cable that end users recognise as their internet service - this has become one of the most developed cable types in IT history. From CAT3 to CAT7, many improvements have been made to improve the quality of the cabling, such as giving it a thicker coating to prevent any EMI, or improving the speeds to move data…
