# What Are The Periodic Signals?

A periodic signal is one that repeats the sequence of values exactly after a fixed length of time, known as the period. In mathematical terms a signal x(t) is periodic if there is a number T such that for all t Equation 10.10 holds.

### What is basic signal?

By Qasim Chaudhari. Classification of continuous-time and discrete-time signals deals with the type of independent variable. If the signal amplitude is defined for every possible value of time, the signal is called a continuous-time signal.

### What is a real signal?

A real signal at any given time takes its value in the set of real numbers, and a complex signal takes its value in the set of complex numbers.

### What are the periodic signals?

A periodic signal is one that repeats the sequence of values exactly after a fixed length of time, known as the period. In mathematical terms a signal x(t) is periodic if there is a number T such that for all t Equation 10.10 holds.

### What is ADC signal?

What is ADC? Analog-to-digital converters, abbreviated as “ADCs,” work to convert analog (continuous, infinitely variable) signals to digital (discrete-time, discrete-amplitude) signals. In more practical terms, an ADC converts an analog input, such as a microphone collecting sound, into a digital signal.

### What is signal example?

A signal is a function or a data set representing a physical quantity or variable. Usually, the signal encapsulates information about the behavior of a physical phenomenon, for example, electrical current flowing through a resistor, sonar sound waves propagating under water, or earthquakes.

### Which of the following pulse modulation is analog Mcq?

Pulse Width Modulation (PWM) or Pulse Duration Modulation (PDM) or Pulse Time Modulation (PTM) is an analog modulating scheme in which the duration or width or time of the pulse carrier varies proportional to the instantaneous amplitude of the message signal.

### What is a signal in science?

A signal is an electrical or electromagnetic current that is used for carrying data from one device or network to another.

### What is an analog signal Mcq?

Analog signal is a continuous signal and digital signal is a discrete signal. A sinusoidal signal is a continuous signal with respect to time. Therefore, sinusoidal signal is a analog signal.

### How are digital signals generated?

Digital signals are patterns generated by sampling a stream of continuous data at regular intervals. The samples or bits of data are converted to a numeric or digit value. The binary code of 1 and 0 used in computers is an example of a digital signal.

An analog input converts a voltage level into a digital value that can be stored and processed in a computer. Why would you want to measure voltages? There are a multitude of sensors available which convert things like temperature, pressure, etc.

### How many inputs does the system have?

Inputs to a system may in theory have any form; however, we will concentrate on four common input types: impulse, step, ramp, and sinusoidal inputs.

### Which system uses Mcq digital?

6. Which system uses digital transmission? Explanation: Though the signal type is analog or digital, the transmission takes place in the digital domain in ISDN and LANs.

### What is signals and its types?

Two main types of signals encountered in practice are analog and digital. The figure shows a digital signal that results from approximating an analog signal by its values at particular time instants. Digital signals are quantized, while analog signals are continuous.

### Which of the following is example of analog data?

A good example of this is an analogue clock. An analogue clock shows the time with a smoothly moving seconds hand. The change is continuous. Sound is also a good example of analogue data.

### What is digital data Mcq?

MCQ: Digital data refers to the information that is. continuous. discrete. bits. bytes.

### What is input signal electronics?

Noun. 1. input signal - signal going into an electronic system. input. signal, signaling, sign - any nonverbal action or gesture that encodes a message; "signals from the boat suddenly stopped"

### What is analog communication?

An analog communication system is a communication system where the information signal sent from point A to point B can only be described as an analog signal. An example of this is Monica speaking to Carl over the telephone, as described in Section 1.2.

### What process converts digital signals into analog signals?

digital-to-analog conversion (DAC), Process by which digital signals (which have a binary state) are converted to analog signals (which theoretically have an infinite number of states). For example, a modem converts computer digital data to analog audio-frequency signals that can be transmitted over telephone lines.

### How are the convolution integral of signals represented?

How are the convolution integral of signals represented? Explanation: We obtain the system output y(t) to an arbitrary input x(t) in terms of the input response h(t). y(t)= ∫x(α)h(t-α)dα=x(t)*h(t).

### What are the advantages of analog communication?

Analog signals are easier to process. Analog signals best suited for audio and video transmission. Analog signals are much higher density, and can present more refined information. Analog signals use less bandwidth than digital signals.
