A 4-bit synchronous counter using JK flip-flops. In a synchronous counter, the clock inputs of the flip-flops are connected, and the common clock simultaneously triggers all flip-flops. Consequently, all of the flip-flops change state at the same time (in parallel). For example, the circuit shown to the right is an ascending (up-counting) four ...
In season 10, episode 8. The episode was filmed most of its scenes to create a better emulation of the game. It went on to win a Primetime Emmy Award for Outstanding Animated Program, becoming the first machinima to win an Emmy. [28] 2007: CSI: Down the Rabbit Hole: Anthony E. Zuiker; Ann Donahue; Carol Mendelsohn; Drama, action: Second Life
aiming down sights (ADS) Also aim down sights. Refers to the common alternate method of firing a gun in a first-person shooter (FPS) game, typically activated by the right mouse button. The real-life analogue is when a person raises a rifle up and places the stock just inside the shoulder area, and leans their head down so they can see in a ...
Frequency divider. A frequency divider, also called a clock divider or scaler or prescaler, is a circuit that takes an input signal of a frequency, , and generates an output signal of a frequency: where is an integer. Phase-locked loop frequency synthesizers make use of frequency dividers to generate a frequency that is a multiple of a ...
The counter itself must count in Gray code, or if the counter runs in binary then the output value from the counter must be reclocked after it has been converted to Gray code, because when a value is converted from binary to Gray code, [nb 1] it is possible that differences in the arrival times of the binary data bits into the binary-to-Gray ...
Ring counter. A ring counter is a type of counter composed of flip-flops connected into a shift register, with the output of the last flip-flop fed to the input of the first, making a "circular" or "ring" structure. There are two types of ring counters:
A stream cipher is a symmetric key cipher where plaintext digits are combined with a pseudorandom cipher digit stream (keystream). In a stream cipher, each plaintext digit is encrypted one at a time with the corresponding digit of the keystream, to give a digit of the ciphertext stream. Since encryption of each digit is dependent on the current ...
