If you are preparing for your GATE exam, you cannot ignore continuous-time signals. Continuous-time signals are also known as analog signals. They are nothing but signals of continuous amplitude and time. If you are taking the GATE ECE exam, then you need to prepare continuous-time signals topics for GATE ECE. With the right direction and comprehensive study materials on the continuous-time signals syllabus for GATE, you can easily crack the exam. As an electrical engineering student, you must be already well acquainted with the topic. However, to do well in your GATE exams, you have to follow the correct approach.

Ques. Is it compulsory to attempt the continuous-time signals GATE questions?

 If you are from electrical or computer science engineering, continuous-time signals questions will form a compulsory part of your paper.

Ques. Are continuous-time signals questions scoring?

Yes. These questions form one of the most scoring sections in your GATE exams. You can easily score full marks if you solve them with full concentration.

Ques. Can I skip the questions from continuous-time signals?

It is not advisable to skip these questions. You can attempt them in the beginning if you have a time constraint. However, ignoring these questions is not a prudent thing to do.

Ques. How do I sample a continuous-time signal?

When you are dealing with functions that vary with time, take a continuous function to sample. Do the sampling by measuring the value of continuous function every t seconds, where t stands for the time interval.

Ques. Is time continuous or discrete?

Time could be any number. It always keeps changing. Therefore, it is a continuous variable.
