Dibal: Design and Implementation of MOD-6 Synchronous Counter using VHDL. AZOJETE, 9: 17-26, 2013 18 the application of VHDL (VHSIC Hardware Description Language) to the design of a MOD-6 counter, the use of the MOD number of a counter to determine the number of flip-flops required will not be looked at in details.

Asynchronous Counters. If the flip-flops do not receive the same clock signal, then that counter is called as Asynchronous counter. The output of system clock is applied as clock signal only to first flip-flop. The remaining flip-flops receive the clock signal from output of its previous stage flip-flop. Hence, the outputs of all flip-flops do ... Aug 10, 2015 · It is a simple counter which can count from 0 – 9. As it is a 4 bit binary decade counter, it has 4 output ports QA, QB, QC and QD. When the count reaches 10, the binary output is reset to 0 (0000), every time and another pulse starts at pin number 9. The Mod of the IC 7490 is set by changing the RESET pins R1, R2, R3, R4.

Binary coded decimal (BCD) counter is a modified binary counter with MOD n = 10. MOD is the number of states that a counter can have. Any counter with MOD = 10 is known as decade counter. It has 10 states each representing one of 10 decimal numbers. Which is why it is known as BCD counter. It counts from 0 to 9 and then it resets ...

For this reason we must design asynchronous modulus counters. An asynchronous modulus counter, or mod-counter, uses the addition of simple combinational logic to a standard asynchronous counter to set the count limit and starting point. In this activity we will simulate and build a mod-5 counter that has a starting count of one. A n-bit ripple counter can count up to 2 n states. It is also known as MOD n counter. It is known as ripple counter because of the way the clock pulse ripples its way through the flip-flops. Some of the features of ripple counter are: It is an asynchronous counter. Different flip-flops are used with a different clock pulse. Synchronous (Parallel) Counters Synchronous (parallel) counters: the flip-flops are clocked at the same time by a common clock pulse. We can design these counters using the sequential logic design process (covered in Lecture #12). Example: 2-bit synchronous binary counter (using T flip-flops, or JK flip-flops with identical J,K inputs). Answer: 3 or 19 or 163 N*16 + 3 (N is unknown) 6 MOD Number The counter in Figure 7-1 has 16 distinct states, thus, it is a MOD-16 ripple counter. The MOD number can be increased simply by adding more FFs to the counter. That is MOD number = 2N Example A counter is needed that will count the number of items passing on a conveyor belt.

PSpice® model library includes parameterized models such as BJTs, JFETs, MOSFETs, IGBTs, SCRs, discretes, operational amplifiers, optocouplers, regulators, and PWM controllers from various IC vendors. Asynchronous or ripple counters. Synchronous counters. The MOD of the ripple counter or asynchronous counter is 2n if n flip-flops are used. For a 4-bit counter, the range of the count is 0000 to 1111. A counter may count up or count down or count up and down depending on the input control. The count sequence usually repeats itself.
