A ring counter is a digital circuit with a series of flip flops connected in a feedback manner. Ring Counter is composed of Shift Registers. The data pattern will re-circulate as long as clock pulses are applied. The circuit is a special type of shift register where the last flip flop's output is fed back to the input of ... WebVerilog Mod-N Counter. Counters are sequential logic devices that follow a predetermined sequence of counting states triggered by an external clock (CLK) signal. The number of states or counting sequences through which a particular counter advances before returning to its original first state is called the modulus (MOD). laporan karya inovatif guru
