(b) Option 2:- Given that a precision analogue temperature sensor produces an output voltage (Vs: sensor output voltage) according to the equation Vs= (43.2mV) T°C + 750 mV. This equation can be expressed in terms of temperature (T) versus sensor voltage (V₂). ie. T = (Vs -0.75)/ 0.0432 °C You are to design the amplifier circuit for this sensor using any combination of inverting amplifiers, non-inverting amplifiers, summing amplifiers (No need to use all types of amplifier) together with a IV reference voltage source. The sensor voltage (V₁) and a 1V reference source (Vref) are the two input signal of your circuit. Your designed circuit should produce an output voltage (V.) to indicate the temperature according to the equation V.= T/10. (°C/10) i.e and When T=0 °C, Vo = OV T = 100 °C, V₁ = 10V.
Quantization and Resolution
Quantization is a methodology of carrying out signal modulation by the process of mapping input values from an infinitely long set of continuous values to a smaller set of finite values. Quantization forms the basic algorithm for lossy compression algorithms and represents a given analog signal into digital signals. In other words, these algorithms form the base of an analog-to-digital converter. Devices that process the algorithm of quantization are known as a quantizer. These devices aid in rounding off (approximation) the errors of an input function called the quantized value.
