An odd (non-symmetric) function of frequency c. A function that is odd and half-wave symmetric d. None of the above. 1 Continuous Wave Modulation Z. Aliyazicioglu Electrical & Computer Engineering Dept. Signal is an electromagnetic or light wave that represents data. Chapter 7 review questions 1.Which signal types are represented by a continuous waveform? Answer: LAN 4. Different forms of communication signals are as follows: Digital signals; Analog signals; Digital Signals. 55) Which among the below mentioned assertions is /are correct? The Sawtooth waveform is commonly available from most function generators and consists of a fundamental frequency ( ƒ ) and all its integer ratios of harmonics, such as: 1/2, 1/4, 1/6 1/8 … 1/n etc. Under the options menu, a Custom waveform can be created and file imported as pattern or play data. These are represented as a sinusoidal waveform. 24) Which signal types are represented by a continuous waveform? Types of Signals. Direction of the charge carriers’ flow changes back and forth. That is, v ( t ) = sin( πt / T ) for 0 ≤ t < T . Types of alternating current waveforms: Features Of An A.C. Waveform For the signal set shown in Fig. The Simple configuration mode for a simple standard signal configuration. changes with time. This type of signal shows continuity both in amplitude and time. 25) To use the analog telephone system for sending digital data, you must also use: A) a modem. In this article we will understand the basic characteristics that make up Electrical Waveforms.. Electrical Waveforms are basically visual representations of the variation of a voltage or current over time.. Continuous-time signals are defined along a continuum of time and are thus, represented by a continuous independent variable. a. analog b. rfid c. optical d. digital? A) Laser B) Optical C) Digital D) RFID E) Analog Answer: E Difficulty: Moderate AACSB: Information technology LO: 7-2: What are the different types of networks? Which type of network is used to connect digital devices within a half-mile or 500-meter dius? These will have values at each instant of time. To use the analog telephone system for sending digital data you must also use Answer: Modem 3. Digital signal is a sequence of voltage represented in binary form. C) DSL. Which signal types are represented by a continuous wave form? The figure below represents an analog signal: As we can see here that the signal is continuous in nature as its every value is specified for each particular interval of time, thus, is referred as the continuous-time signal. The data symbols for the signal set of Fig. Direction of current flow in the electrical circuits varies with time in a periodic manner. Signals are used to transfer data from one device to another through a communication medium. These types of signal waveform are used for either timing signals, clock signals or as trigger pulses. The positive ramp Sawtooth Waveform is the more common of the two waveform types with the ramp portion of the wave being almost perfectly linear. Answer: Analog 2. Which type of network serves as a small group of computers allowing … a. 3A are d 0 = 1 and d 1 = 0, so this is an orthogonal signal set. Cal Poly Pomona ECE 405 Continuous Wave Modulation A modulation is a process of transforming a baseband signal (message) to another signal called modulated waveform.The demodulation is the process of recovering the baseband signal Continuous-time signals are often referred to as analog signals. 3D, the basic waveform is the sine pulse, which is one-half of a full period of a sine wave. 54) The ESD of a real valued energy signal is always _____ a. An Analog Signal is a continuous signal, just like an electric current that flows through the copper cables when your electrical appliances are turned on. B) a router. Type represents the standard signal types: DC, Sine, Square, Triangle, Ramp-Up, Ramp-Down, Noise, Trapezium, and Sine-Power. Types of direct current waveforms: Alternating current means that the polarity of the e.m.f. ANSWER: (a) An even (symmetric) function of frequency. Continuous Time Signals.
