oscillator frequency การใช้

• In that case, only the local oscillator frequency is changed.
• This in turn is integrated to find the oscillator frequency.
• This resulted in detector manufacturers responding by changing their local oscillator frequency.
• Resolution of a single count is generally proportional to the timebase oscillator frequency and the gate time.
• In this application, the transistor is made to self-oscillate at the local oscillator frequency.
• The local oscillator frequency determines what block of incoming frequencies is downconverted to the frequencies expected by the receiver.
• There are two choices for the local oscillator frequency because the dominant mixer products are at " f"
• He invented a quartz-crystal oscillator frequency standard in 1930, and patented a temperature control oven for crystal oscillators.
• The local oscillator frequency is switched in response to a 22 kHz signal superimposed on the supply voltage from the connected receiver.
• Most receivers are actually superheterodyne receivers and they leak a little of their local oscillator frequency; this can be easily detected.
• Corresponding oscillator frequencies of the nerve cells would then refer to the same object, while other frequencies would mark other objects.
• That carrier and the two frequencies ( that the sweep changed between ) were generated as multiples of the same basic oscillator frequency.
• Both the on-board oscillator frequency ( if used ) and the PLL multiplier value may be changed at run-time.
• Viewed another way, the received signal frequency is doppler shifted from the oscillator frequency by the relative motion of the fuze and target.
• Where \ omega _ { 0 } and b are constants, namely, the time-averaged oscillator frequency and damping, respectively.
• Since the frequency is referenced to the receiver time, the uncertainty in the receiver oscillator frequency adds to the frequency range of the search space.
• A PLL includes a phase detector, filter and oscillator connected in a closed loop, so the oscillator frequency follows ( equals ) the input frequency.
• Placing the oscillator in a temperature-controlled " oven " at a constant but higher-than-ambient temperature is another way to stabilize oscillator frequency.
• If the local oscillator frequency is less than the desired reception frequency, it is called "'low-side injection "'( " f"
• A control was used to tune the local oscillator frequency until the blips on the display stopped moving, which meant the local and master oscillators now had the same timing.
