Responses and Stability
Responses and stability are crucial aspects in the field of electronics and communication (EC). The study of responses focuses on understanding how electronic systems behave in different situations, such as transient and steady-state conditions. Stability analysis, on the other hand, examines the ability of a system to maintain its desired performance over time. Mastering these concepts is essential for GATE EC aspirants, as they form the foundation for designing and analyzing electronic circuits and systems. By studying responses and stability, candidates can gain insights into the behaviour of electronic systems and develop the skills necessary to ensure their reliable and efficient operation.

Impulse Response and Location of Poles of Transfer Function in s-plane
Understanding the impulse response and the location of poles of a transfer function in the s-plane are crucial aspects of system analysis and design. These concepts provide insights into the system’s time-domain behaviour and stability characteristics, allowing engineers to make informed decisions.
- Impulse Response h(t):
h(t) Ae-at u(t); a>0
Transfer Function H(s) = L{h(t)}: Pole at s = -a ROC isσ > -a Where σ is the real part of s.
Location of Poles in s-plane and ROC
The location of poles in the s-plane and the Region of Convergence (ROC) are key concepts in the field of signal processing. They provide insights into the stability, behaviour, and frequency response characteristics of systems represented by Laplace transforms.
- Impulse Response h(t):Ae-at u(-t); a>0
- Impulse Response h(t):h(t) Aeat u(t); a>0
- Impulse Response h(t) :h(t) Aeat u(-t); a>0
- Impulse Response h(t) :h(t) Ae-a|t|; a>0
- Impulse Response h(t) :
- Impulse Response h(t): h(t) A u(t)
- Impulse Response h(t): h(t) = At(u)t
- Impulse Response h(t):h(t) = 2A cos bt u(t)
- Impulse Response h(t):h(t) = 2Aebt cos bt u(t) where a > 0
- Impulse Response h(t): h(t) = 2At cos bt u(t)
