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.
Determine and plot for 5 keV to 100 MeV the fraction of the total cross section due to each of the four interaction processes for (a) hydrogen, (b) nitrogen,
Q. Use of N-channel JFET? Generally, N-channel JFETs are more commonly used than P-channel. With no voltage applied between gate and source, the channel is a wide-open path for
Current Source Inverter (CSI) Current source inverter has constant input but it can be adjusted. In CSI the amplitude of output current is independent of load. The lo
In order to demonstrate aliasing, make a plot of the signal x(t) = 3 cos 2π10t - cos 2π30t which approximates a square wave with W = 30 Hz. If the sample points are taken at
3-phase 3 wire meter with CT and MD It is exactly such as 3-phase 4 wire meter and works on the similar principle. It is also used in the similar way and under the similar cir
Is there an opto-coupler that has a blocking voltage, VRRM, of greater than 800 volts? Perhaps, 1200 or 1600 volts? The manufacturer?
Why do we use XRA A instruction The XRA A instruction is used to clear the contents of the Accumulator and keep the value 00H.
Q. Design the high-pass filter shown in Figure (by determining C) to have a half-power frequency of 1 MHz.
Magnetic circuits To see how this is used in practice, consider a coil of N turns wound onto a closed ring shaped former with a very high (note: r (steel) = 200
