Definitions A synchronous circuit is a sequential circuit whose input/output changes are synchronized by a reference signal called clock signal. Basic synchronous circuits include: Counters (sequential circuits configure in a specific form in order to count clock ticks). Registers (for elementary storage and shift operations) Random-Access Memories (RAMs) for Read/write operations.

Basic Synchronous Circuits Characteristics: Clocked by stable clock signal (crystal oscillator) Set of input and output data lines Set of control signals Can be described using FSMs Can be implemented using basic synchronous cells (DFFs and JKFFs). Exist as MSI (medium scale integrated) circuits. Their designs often require the use of some combinational elements.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
