What is the minimum frequency at which the sig alog converter (ADC) has a step size of 0.0075V and a fu timum quantization error for this ADC if the ECG signal ranges signal is samples at 80 samples/second. What frequency will be "alia to 100 Hz, although no contains components with frequencies up ained at frequencies above 40 Hz. the min (1 Mark) C) A certain digital-to-analog...
A process of manufacturing yields items of which 1% are defective . A quality control plan is to select 100 items from the process, and if less than 2 are defective, the process continues. USE the normal approximation to the binomial to find the prob. that the process continues fives the sampling described.
Equation B provides an approximation of Equation A, based on the small angle approximation This approximation is said to be vaild for angles up to 30. Complete the table below to convince yourself of the quality of your experiment. Comment on your results Table 4: Quality of Approximation Initial Angle We define period of a the time required for a complete oscilation. Since the lrthe·ngle θ is small, less than 30, i. equation A the terms in sineandsmsarse mall that...

1- Figure below shows the temperature characteristic of a temperature sensor. Deduce the amplifier gain you would consider in order to convert the signal of the sensor with a minimum quantization errors. Assume that only 5DC power supply is available. A Output Voltage (mV) O- 10 80 °C Temperature (°c) 2- Provide an appropriate value of the ADCON2 register if the temperature sensor has a response delay of 20 us and if the PIC18 microcontroller has an intrinsic delay of...
An analog signal ?? (?) = 6sin(280??) + 3 sin(720??) − 7cos 260(? − 1)? is sampled 400 times per second. (a) Determine the Nyquist sampling rate for ?? (?). (b) What are the frequencies, in radians, in the resulting discrete-time signal ?(?). (c) What is the quantization step size? (assume L=10) (d) What is the dynamic range of the signal.
1) Does the quality factor depend on the frequency of the original AC signal? 2) How can the quality factor of the rectifier circuit be increased?
3. The quality of a received signal is often characterized by the signal-to-noise-ratio (SNR), which is defined as SNR 10 log As you might expect from this Signal power in watts KTB definition, the unit of SNR is decibels (dB). The term in the denominator is the noise power, and it is generally specified as an effective noise temperature T multiplied by the product of Boltzmann's constant (K) and the bandwidth (B) of the signal in Hz. Generally we like...
