Typical analog inputs and outputs can vary from. D Successive-approximation analog-to-digital converter. 0-20 mA 0-20 mA 0-10 V.

In contrast a digital signal represents the original time-varying quantity as a sampled sequence of quantized values. In short to understand analog signals all signals that are natural or come naturally are analog signals. B Music signal processing.

MCQ from Number 1 50 Answer key. An analog signal is sent in discrete pulses in two states on 1 or off 0. An analog signal is any continuous signal representing some other quantity ie analogous to another quantity.

An analog signal can never be converted into a binary signal. An analog signal is usually continuously changing in value. The analog signals were used in many systems to produce signals to carry information.

Digital circuits are manufactured at a fraction of the cost. The digital signal contains the digital values converted from the analog signal at the specified time instants. 131 What is the value of carrier frequency in the following equation for the FM signal.

The difference between the highest and lowest input frequency. B-An analog audio signal is measured at regular intervals. C Digital-ramp analog-to-digital converter.

B Dual-slope analog-to-digital converter. Accept signal from field devices and convert them into signals that can be used by the processor. Using descriptive text to.

In other words analog signals are analogous to some other time-varying signal. A Show that x t is periodic and obtain its period. A-An analog audio signal is measured as input parameters to a program or procedure.

Following is the list of multiple choice questions in this brand new series. When we speak we use air to transmit an analog signal. Digital circuits are typically easier to design using ICs.

Analog and Digital DRAFT. Carries more detailed information. Digital to analog.

The use of analog signals has been declined with the arrival of digital signals. For example in an analog audio signal the instantaneous signal voltage varies continuously with the pressure of the sound waves. An analog signal has a discrete number of states.

B Use Parsevals theorem to find its average power. The sine waves. There should not be any discrete value changes see Figure 1.

Vt 5 cos6600t 12sin2500t a. Digital and Data Communication Networks MCQs. Here the instantaneous voltage associated with the analog signal continuously varies with the pressure associated with the sound waves.

Less prone to interference. Digital startstop synchronous serial interface various flavors of fieldbus and so on. On the ADC evaluation board use a clean signal generator with low phase noise to provide an input signal to the input channel J100.

A big disadvantage of digital technology is the recording does degrade over time. C If x t is transmitted through a telephone system which blocks DC and frequencies above 12 kHz compute the ratio of received to transmitted power. A signal having the characteristic of being continuous and changing smoothly over a given range rather than switching suddenly between certain levels.

Analog signals in the real world include current voltage temperature pressure light intensity and so on. Sure there are all kinds of other sensor interface types available. These signals are continuous in both values and time.

An analog signal is the only way that music can be recorded. MCQ from Number 51 100 Answer key. A Single-slope analog-to-digital converter.
