2003年1月27日 · Re: MIPS + MHz Hi, MHz (Megahertz) is the number of clock cycles every second. This is usually determined by a crystal oscillator on the board somewhere. For instance, if your processor or memory runs at 20MHz, it gets 20 million clock cycles every second. What it does with this depends entirely on the chip.

4.194304 X Real-time clocks, divides to 1 Hz signal (222×1 Hz) 4.332 RDS The RDS signal bit rate is at 1.1875 kbit/s. While the frequency of 4.332 MHz is the most commonly used crystal resonator, its multiples (2×4.332 MHz = 8.664 MHz or 4×4.332 MHz = 17.328 MHz) have been used also. 4.43361875 PAL/NTSC PAL B/D/G/H/I and NTSC M4.43 color ...

2006年8月18日 · Other common units are Bytes/second (Bps or B/s; often incorrectly abbreviated bps; 1 B/s = 8 bps exactly) and Hz (a common 16-bit bus has a frequency of 8 MHz = 64 Mbps; a voice stream digitized by the phone company has a bandwidth of exactly 64 000 bps and roughly 4 KHz). As you can see, converting between Hz and bps is not trivial.

2006年11月26日 · Because spectrum is not flat, for oscillators the noise is given as dBc/Hz at x KHz offset from central frequency. An unit as dB/MHz is usefull only if the noise power is quite constant in a 1MHz bandwidth, egg thermal noise, but not for an oscillator.

2014年9月30日 · Where do you see UWB spectral power definitions in FCC with GHz bandwidth? There are specifications with 1 kHz, 1 MHz and 50 MHz resolution bandwidth. Also respective ETSI specifications are using similar limit values. Calculating dBm/Ghz spectral density is possible but doesn't seem to make much sense.

2010年4月9日 · Can anyone provide me code to generate a 1hz frequency clock generator from vhdl with clock cycle of 100Mhz default. please.

2012年12月31日 · I want to know the relation between sampling frequency (Hz) and sampling rate (sample per second). For example, a 1 Hz sin wave sampled at 8000 samples per second. Each cycle of the 1Hz tone will span all 8000 samples (since its period is 1 second). Thus sampling period will be 1/ (8000-1) s Or sampling frequency will be 8000-1 ≈ 8000Hz.

2012年3月22日 · you want 2.048MHz. which is 2**14 * 5**3 (2**11 * 1000) for the very slow clocks, this will work. Keep in mind that any signals passing between the "fast" clock and slow clock domains may need to meet timing.
