About this pack

Scope

A formula and reference sheet for the Digital Logic part of the GATE CS 2027 syllabus, organised as topic mini-sheets: Boolean algebra and canonical forms; minimisation with K-maps and the tabular method; combinational building blocks; flip-flops, counters and state machines with timing; number systems, complements and overflow; floating point in IEEE 754. Each card states the relation, what every symbol means, the conditions under which it holds and the mistake students make with it. Tables collect the laws, flip-flop characteristic and excitation rows, counter state counts, number ranges for every signed form and the IEEE 754 special values. Worked examples cover a minimisation with don't-cares, a prime implicant count, an overflow check, a clock-rate limit and a full IEEE 754 encoding. A final page collects the pairs students confuse and a Last-Minute Recall list. Every worked number on the sheet was recomputed by a script. It is a revision aid for students who have already studied the topics; it does not replace a textbook or a course.

Before you buy

Common questions

What exactly will I receive?

A 8-page A4 PDF in two editions: a screen edition for reading on a device and a print edition prepared for A4 printing. Nothing is shipped; it is a download.

Can I read it on my phone, and can I print it?

Yes. The PDF opens in any PDF reader on phones, tablets and computers, and the bookmarks jump between pages. You may print it for your own study.

Is it for GATE 2027?

Yes. The packs follow the official GATE CS 2027 syllabus, and each pack says what is in scope and what is covered in another pack. GATE CS Mastery is independent and not affiliated with IIT, IISc or the GATE organising committee.

How is this different from ordinary short notes?

Each page answers one question and uses labelled boxes: rules with their conditions, traps with the fix, comparison tables and small worked examples. Every pack ends with a traps sheet, a question-patterns sheet and a one-page last-day sheet.

What happens after I pay?

When Razorpay confirms the payment, download buttons appear straight away and a receipt is emailed to you. Later, My library sends a one-time link to your purchase email and shows fresh download links.

What if the payment succeeds but the download fails?

Do not pay again. Your purchase is recorded as soon as the payment is verified. Open My library, or write to support@gatecsmastery.com with your order ID or Razorpay payment ID. See the refund policy for when a refund applies.
