Explain the meaning of Ring Counters?
A ring counter is fundamentally a circulating shift register in which the output of the most significant stage is fed back to the input of the least significant stage.
The following is the 4-bit ring counter constructed from D flip-flops and the output of each stage is shifted into the next stage on the positive edge of a clock pulse and if the CLEAR signal is high all the flip-flops except the first one FF0 are reset to 0. FF0 is preset to 1 in its place.
Ever since the count sequence has 4 distinct states the counter can be considered as a mod-4 counter. The Only 4 of the maximum 16 states is used in making ring counters very inefficient in terms of state usage. Except the major advantage of a ring counter over a binary counter is that it is self-decoding. No extra decoding circuit is required to determine what state the counter is in.
L filters: An L filter contains two reactive elements that are one in series and one in parallel. T and π filters: Main article: Capacitor-input filter
The Series Resistance rule
Circuits, which provide sinusoidal waveforms, are but useful in themselves and form the basis of many other circuits, such as square and triangular waveform generators, and clocks.
TRAP has the maximum priority There are 2 types of interrupts external and internal. NMI has highest priority between all external interrupts,TRAP has highest priority between
