(NYSE:TRW), a world leader in advanced semiconductors, has developed a highly efficient microwave power amplifier chip that delivers world record levels of power per unit of semiconductor area for integrated circuits operating at more than 20 billion cycles per second
The transmitter section of the radar has a patented circuit, which generates ultra-wideband pulses with an approximate bandwidth of four gigahertz (GHz) (billion cycles per second
) at a rate of five megahertz (MHz) (million cycles per second
) and an average power of about 100 micro watts.
Bluetooth achieves its wireless communication over the 2.4 gigahertz (GHz) radio band, or 2.4 billion cycles per second
. By comparison, a typical AM radio station operates in the kilohertz (kHz) range, or thousands of cycles per second
Goodbye Lice uses dual combs, moving opposite each other at over 200 cycles per second
, to detangle hair and quickly remove lice and nits without potentially harmful chemicals or electric shocks.
"The new tool and its open API enable our customers to easily develop their own multicore simulation platforms by integrating their favorite processor cores and peripherals and simulate with full cycle-accuracy and at speeds of tens of thousands cycles per second
for complex targets," said AXYS' president Vojin Zivojnovic.
The unit has dual combs that move opposite each other at a rate of 200 cycles per second
. Emjoi suggested that the product could be used as a preventive measure as well, to be used before a lice problem fully develops.
Alternating current is actually changing direction, or polarity, 60 times or cycles per second
. Looks like this (-).
In the same issue of Byte Magazine, John Kelly, a Vice President with IBM, said that "with CMOS (complementary metal-oxide semiconductor) technology and a lot of hard work, in a decade we'll be using X-ray lithography and other techniques to deliver a (micro)processor that has 50,000,000 to 100,000,000 transistors and operates at 1 gigahertz (1 billion cycles per second
)." For comparison, the current Pentium Pro microprocessor includes 5.5 million transistors and operates at 200 megahertz (200 million cycles per second
Another problem is cycles per second
. In the United States, alternating current changes direction sixty times per second; in much of Europe, the current changes at fifty cycles per second
radio waves with frequencies of between 2 and 50 GHZ (thousand million cycles per second
In color cameras, however, the vertical sync rate must be changed from 60 to 59.94 cycles per second
. Although that may not seem like a great change, the resulting effect makes it impossible to synchronize color cameras in a system by using the same method applied to black-and-white cameras.
