सीक्वेंशियल परिपथ के संबंध में निम्नलिखित कथनों पर विचार कीजिए:
1. सीक्वेंशियल परिपथ वर्तमान इनपुट और मेमोरी अवयवों में संग्रहीत पिछली अवस्थाओं दोनों पर निर्भर करते हैं।
2. ऐसे सिस्टम में फ्लिप-फ्लॉप और लैच संग्रह क्षमता प्रदान करते हैं।
3. सभी सीक्वेंशियल परिपथ अनिवार्य रूप से असिंक्रोनस होते हैं।
उपरोक्त में से कौन-सा/से कथन सही है/हैं?
उत्तर और चरणबद्ध हल
सीक्वेंशियल परिपथ लॉजिक और मेमोरी को जोड़ते हैं, इसलिए आउटपुट/अवस्था वर्तमान इनपुट और पिछली अवस्था पर निर्भर करती है। फ्लिप-फ्लॉप और लैच संग्रह देते हैं। मुख्य संबंध: x[k+1]=F(x[k],u[k]); y[k]=G(x[k],u[k])।
परीक्षा फोकस: सीक्वेंशियल ≠ असिंक्रोनस; सिंक्रोनस सीक्वेंशियल परिपथ भी होते हैं।
विस्तृत हल (मूल भाषा में)
Statement-wise Verification
- Statement 1 - Correct.
Sequential circuits depend on both present inputs and previous states stored in memory elements.
Sequential circuits combine logic with memory, so outputs/state depend on present inputs and previous state. - Statement 2 - Correct.
Flip-flops and latches provide storage capability in such systems.
Flip-flops and latches provide storage. - Statement 3 - Incorrect.
All sequential circuits are necessarily asynchronous in operation.
Sequential circuits may be synchronous or asynchronous
Core Concept
Sequential circuits combine logic with memory, so outputs/state depend on present inputs and previous state. Flip-flops and latches provide storage. Sequential systems can be synchronous, driven by a clock, or asynchronous; being sequential does not imply asynchronous operation.
Formula / Key Relationship
x[k+1]=F(x[k],u[k]); y[k]=G(x[k],u[k]).
Why the Other Options Are Wrong
Option B is incorrect because it includes incorrect statement(s) 3 and omits correct statement(s) 1. Option C is incorrect because it includes incorrect statement(s) 3 and omits correct statement(s) 2. Option D is incorrect because it includes incorrect statement(s) 3.
Exam Shortcut / Approach
Look for state/memory before classifying a circuit as sequential.
Common Mistake
Do not equate 'sequential' with 'asynchronous'.

Consider the following statements regarding Sequential circuit:
1. Sequential circuits depend on both present inputs and previous states stored in memory elements.
2. Flip-flops and latches provide storage capability in such systems.
3. All sequential circuits are necessarily asynchronous in operation.
Which of the above statements is/are correct?
Answer & step-by-step solution
Sequential circuits combine logic with memory, so outputs/state depend on present inputs and previous state. Flip-flops and latches provide storage. Key relation: x[k+1]=F(x[k],u[k]); y[k]=G(x[k],u[k]).
Exam focus: Look for state/memory before classifying a circuit as sequential. Common trap: Do not equate 'sequential' with 'asynchronous'.

સિક્વેન્શિયલ પરિપથ સંબંધિત નીચેના વિધાનો ધ્યાનમાં લો:
1. સિક્વેન્શિયલ પરિપથ વર્તમાન ઇનપુટ અને મેમરી ઘટકોમાં સંગ્રહિત અગાઉની અવસ્થાઓ બંને પર આધાર રાખે છે.
2. આવી સિસ્ટમમાં ફ્લિપ-ફ્લોપ અને લેચ સંગ્રહ ક્ષમતા પૂરી પાડે છે.
3. બધા સિક્વેન્શિયલ પરિપથ અનિવાર્ય રીતે અસિંક્રોનસ હોય છે.
ઉપરોક્તમાંથી કયું/કયા વિધાન સાચું/સાચા છે?
જવાબ અને પગલાવાર ઉકેલ
સિક્વેન્શિયલ પરિપથ લોજિક અને મેમરીને જોડે છે, તેથી આઉટપુટ/અવસ્થા વર્તમાન ઇનપુટ અને અગાઉની અવસ્થા પર આધાર રાખે છે. ફ્લિપ-ફ્લોપ અને લેચ સંગ્રહ આપે છે. મુખ્ય સંબંધ: x[k+1]=F(x[k],u[k]); y[k]=G(x[k],u[k]).
પરીક્ષા મુદ્દો: સિક્વેન્શિયલ ≠ અસિંક્રોનસ; સિંક્રોનસ સિક્વેન્શિયલ પરિપથ પણ હોય છે.
