Is signal and system hard Quora?
Signals and Systems should not be a hard class. At start every subject feels difficult. Over a period of time you will start understanding few things. As you spend time, lot of things will get clear.
How do I prepare for signals and systems Quora?
Signals and systems is the most basic subject. So read the concepts first from a standard text book like Oppenheim. Make short notes of all important formulas and concepts. After finishing each topic start solving problems on that topic from Kanodia and also keep studying a new topic from text book side by side.
Are Signals and Systems tough?
In Signals and Systems people usually face difficulty due to lack of physical intuition. All these fourier transforms and series become difficult when u dont understand what is happening physically…. If you want physical intuition then spend time on it….
How difficult is Signals and Systems?
Abstract: The introductory continuous-time signals and systems (CTSS) course is widely considered one of the most difficult courses in electrical and computer engineering (ECE) curricula.
Why is Signals and Systems so hard?
Why do we study signal and systems?
Invariably, one will find that Signals and Systems is taught as a core subject. The reason for this is because the concepts of Signals and Systems form the foundation upon which the theories and techniques of many later year subjects that are studied in electrical engineering are developed.
What is application of signal and system?
Examples of systems that manipulate signals are speech recognition, video streaming, cellular networks and medical scans such as MRI. The disciplines of signal and image processing are concerned with the analysis and synthesis of signals and their interaction with systems.
What is application of signal processing?
DSP is used primarily in arenas of audio signal, speech processing, RADAR, seismology, audio, SONAR, voice recognition, and some financial signals. For example, Digital Signal Processing is used for speech compression for mobile phones, as well as speech transmission for mobile phones.
Why signal and system is important?
What is a system in signal and system?
Signals and Systems. A signal is a description of how one parameter varies with another parameter. For instance, voltage changing over time in an electronic circuit, or brightness varying with distance in an image. A system is any process that produces an output signal in response to an input signal.
Is signal processing hard?
DSP is hard for all the reasons already given, but also because you are doing something hard. in fact, once you get the hang of it, your attitude will flip and you will realise it is an easy way to tackle difficult problems.
Is signal processing a good field?
So, yes, it is extremely good to have a degree in applied math to be a successful communication or signal processing engineer.
What are acceptable output voltages for a gate?
“Acceptable” output signal voltages (voltage levels guaranteed by the gate manufacturer over a specified range of load conditions) range from 0 volts to 0.5 volts for a “low” logic state, and 2.7 volts to 5 volts for a “high” logic state:
How do you use a timer on a commercial gate?
For example, use a timer to hold open a commercial gate between 7 AM – 5 PM on weekdays. To enhance security, another usage for a timer is to disable keypad or radio remote access during night hours but allow entrance with a proprietary key switch, which is left active.
What is the output voltage range of the TTL gate?
The guaranteed output voltage range of 2.7 volts to 5 volts from the TTL gate output is nowhere near the CMOS gate’s acceptable range of 7 volts to 10 volts for a “high” signal.
How does a TTL gate work with a CMOS inverter gate?
Take for instance a TTL NAND gate outputting a signal into the input of a CMOS inverter gate. Both gates are powered by the same 5.00 volt supply (V cc ). If the TTL gate outputs a “low” signal (guaranteed to be between 0 volts and 0.5 volts), it will be properly interpreted by the CMOS gate’s input as a “low”…
