Difference between discrete and digital signal?
THE TERM CONTINUOUS SIGNAL AND DISCRETE SIGNAL CLASSIFY THE SIGNALS ALONG THE TIME (i.e. horizontal axis) where as THE TERM ANALOG AND DIGITAL SIGNAL CLASSIFY THE SIGNAL ALONG THE AMPLITUDE (i.e vertical axis) we often confuse our-self with continuous time and analog signals. An analog signal is a signal which can take any amplitude in continuous range that is signal amplitude can take infinite values on the other hand a digital signal is one whose amplitude can take only finite numbers of values
What are the properties of signals?
Signals possess several key properties, including amplitude, frequency, phase, and duration. Amplitude refers to the strength or intensity of the signal, while frequency indicates how often a signal oscillates over time. Phase describes the position of the waveform in time, and duration refers to how long the signal lasts. Additionally, signals can be classified as analog or digital, depending on whether they represent continuous or discrete values.
When signal amplitude is zero?
When signal amplitude is zero, it indicates that there is no variation in the signal's strength or intensity at that moment, effectively meaning the signal is not present or is at its baseline level. This can occur in various contexts, such as audio signals, where it signifies silence, or in electrical signals, where it may indicate a lack of voltage or current. In digital communications, a zero amplitude can represent a logical "0" or an absence of a transmitted signal. Overall, a zero amplitude can signify a critical state in signal processing, possibly indicating an issue or a specific operational condition.
What converts digital signals into analog signals for use with IDSN?
it is an DAC (Digital to analogue converter
Do dvi-i inputs use digital or analog signals?
digital
What three types of signals are carried by radio waves?
Radio waves carry three main types of signals: analog signals, digital signals, and modulated signals. Analog signals transmit continuous variations in amplitude or frequency, while digital signals convey information in discrete binary form. Modulated signals, which can be either amplitude modulation (AM) or frequency modulation (FM), are variations of these basic types that encode information onto a carrier wave for efficient transmission over distances.

How can a digitizer graph be used to convert analog signals into digital signals?
A digitizer graph can be used to convert analog signals into digital signals by sampling the analog signal at regular intervals and assigning numerical values to the sampled points. These numerical values represent the amplitude of the signal at each sampled point, allowing the analog signal to be represented in a digital format that can be processed and stored by a computer or other digital device.

Why you need modems on digital circuits?
In digital circuits modem is used to multiplex and demultiplex the digital data.multiplexing means the digital signals amplitude or frequency or phase is varied with a carrier signal.at the receiver end the carrier signal is separated out and original digital signal is received

Is sound signal a digital signal?
Sound signals are typically analog signals because they represent continuous waveforms that vary in amplitude and frequency. However, when sound is converted into a digital format through sampling and quantization, it becomes a digital signal. This digital representation can be processed, stored, and transmitted by digital devices. Thus, while sound itself is inherently analog, it can be transformed into a digital signal for various applications.
What is the difference between AM and ASK?
Amplitude Modulation (AM) and Amplitude Shift Keying (ASK) are both techniques used in communication systems, but they serve different purposes. AM is an analog modulation technique where the amplitude of a carrier wave is varied in proportion to the instantaneous amplitude of the audio signal, typically used in radio broadcasting. In contrast, ASK is a digital modulation scheme where the amplitude of the carrier signal is switched between two levels to represent binary data, making it suitable for digital communication systems. Essentially, AM is used for analog signals, while ASK is used for transmitting digital information.
What is the difference between the AM modulation and ASK modulation?
This is hard to explain. AM means amplitude modulation, while ASK is amplitude-shift keying. AM is usually analog as it is modulated based on the strength of the signal, though you can use it to send a digital signal. ASK represents digital data as variations in the amplitude of a carrier wave. Any digital modulation technique will represent the data using a finite number of different signals. While AM is used mostly for radio and television, ASK is used for telegraph signals, transmission across telecommunications equipment, and fiber optics.
How are digital signals?
Digital signals are measured in bits per second (bps).
What are the values that digital signals have?
digital signals have two values. 0 and 1.
What do you use to measure an ampitude?
Amplitude is typically measured using a signal processing tool known as an oscilloscope. An oscilloscope visually represents the magnitude of a signal over time, allowing users to measure the amplitude of a waveform accurately. Additionally, digital multimeters and spectrum analyzers can also be used to measure amplitude in electrical signals.
