Analog data attempts to be continuous and identify every nuance of what is being measured, while digital data uses sampling to encode what is being measured. Step-by-step explanation: When distinguishing between quantitative variables, they could be classed as either discreet or continuous. The sender sends the message over the data channel to the receiver, The receiver is the destination of the message. And if we can measure something to a (theoretically) infinite degree, we have continuous data. The data are discrete because the data can only take on specific values. Explanation: Discrete variables are those that can take only a finite number of values. There are a few important things to know about continuous data. Analog to Digital Converter (ADC) driver software usually captures a single block of samples; if a larger dataset (or continuous stream) is required, it can be very difficult to merge multiple blocks without leaving any gaps. B. *Response times may vary by subject and question complexity. The numbers of languages spoken by different people Choose the correct answer below. The continuous data can be broken down into fractions and decimals, i.e. For example, it might be a collection of heights, times or weights. Analog communication systems are less sensitive in terms of electrical tolerance. Hybrid computer has features of both analogue and digital computer. Digital data: Discrete state information. Continuous data are measurements that if placed on a number scale, can be placed in an infinite number of spaces between two whole numbers. Some data are continuous but measured in a discrete way e.g. The data are continuous because the data can take on any value in an interval Determine whether the given value is a statistic or a parameter. Temperature. . For example, height can be measured as whole numbers . Here are the modes of Data transmission in communication. That is, a member of this set (element) that must appear between any two initial elements of the set, has an infinite possible points/positions to take in the space between the initial two elements. This is probably because it can be categorized into separate groups, (e.g. An analogue-to-digital (A/D) converter is a computer controlled voltmeter which can be made to measure a voltage signal and return a number which can be stored in computer memory. Analog data is not easily searchable, because it needs to be scanned manually in order to get the desired information. If we count something, like defects, we have gathered discrete data. An analog signal is a continuous signal whereas Digital signals are time separated signals. . O A. It may take any numeric value, within a potential value range of finite or infinite. Data and Signals Data must be transformed to electronic signals (why?) Median response time is 34 minutes for paid subscribers and may be longer for promotional offers. according to measurement accuracy, it can be significantly subdivided into smaller sections. fig 1. Different stations signal to avoid intermixing, each low pass signal must be shifted to a diverse range on the frequency band. O A.
