clock signal is connected to the clock input of the first flipflop.The clock input of the remaining flipflop is triggered by output of the previous stage.
Counter circuits made from cascaded J-K flip-flops where each clock input receives its pulses from the output of the previous flip-flop invariably exhibit a ripple effect, where false output counts are generated between some steps of the count sequence. These types of counter circuits are called asynchronous counters, or ripple counters.
in a cascaded arrangement,when tha output of 1 flipflop is given as the clock pulse of the next flipflop ts called as asynchronous closk pulse..i.e.ts not a simultaneous clock pulse.
the clock pulse is not common
ReplyDeleteif clk is not common ...then it is asychronous

ReplyDeleteit means different clock pulse.
ReplyDeleteasynchronous counters are also called ripple counters.In these counters the transition of the first stage ripples through to the last stage.
ReplyDeleteclk is not common
ReplyDeleteit refers to different clock pulse
ReplyDeleteIf the clock pulse is not given simultaneously to the flip flops then it is called asynchronous in counters...
ReplyDeletewhen the clock pulse is not known
ReplyDeleteWHEN THE CLOCK PULSE IS GIVEN RAMDOMLY TO THE FLIPFLOPS...IT IS CALLED AS ASYNCHRONOUS IN COUNTERS...
ReplyDeleteasynchronous refers to events that do not have a fixed time relationship with each other and generally do not occur at the same time.
ReplyDeleteasynchronous means that only one clock pulse is used to drive the whole counter...
