crystal oscillator
The COHO (Coherent Oscillator) in an MTI (Moving Target Indicator) radar typically uses a local oscillator frequency that is twice the radar's operating frequency. This frequency is used in the radar's mixer stage to enable the detection and tracking of moving targets.
The vacuum frequency is the natural frequency of an oscillator in a vacuum, which is given by f = 1/(2π√LC), where L is the inductance and C is the capacitance. The Q-factor in vacuum, Qvac, represents the quality factor of the oscillator in a vacuum, indicating the ratio of energy stored to energy dissipated per cycle.
No, the frequency of a harmonic oscillator does not depend on its amplitude. The frequency is determined by the properties of the system, such as mass and spring constant, and remains constant regardless of the amplitude of the oscillation.
The fundamental frequency of oscillation in a piezoelectric oscillator is given by the formula f = v/2L, where v is the velocity of longitudinal waves in the crystal and L is the length of the crystal. Plugging in the values, we get f = (5.5 x 1000)/(2 x 0.05) = 55000 Hz. So, the fundamental frequency of oscillation in the piezoelectric oscillator is 55000 Hz.
Yes, megahertz (MHz) is a unit of frequency that represents one million cycles per second. It is commonly used to measure the clock speed of a computer processor or the frequency of a radio wave.
A superheterodyne receiver is a Radio Frequency receiver method that multiplies the received signal frequency with a local oscillator frequency to get frequencies that are the sum and difference of the 2 frequencies. For example, if the received signal is 5MHz and the local oscillator frequency is 4MHz, they are multiplied together. 1MHz and 9MHz frequencies would be gotten. Usually the 1MHz is the Intermediate Frequency (IF). It will be admitted (through a band pass filter) later passed through the required electronic circuits for proper processing. There is also the method of the Variable Tuned Filter.
1MHz
A local oscillator is an electronic device used to generate a signal normally for the purpose of converting a signal of interest to a different frequency using a mixer. This process of frequency conversion, also referred to as heterodyning, produces the sum and difference frequencies of the frequency of the local oscillator and frequency of the input signal of interest. These are the beat frequencies. Normally the beat frequency is associated with the lower sideband, the difference between the two.
depends on the oscillator and its purpose
clapp oscillator have frequency more stable and accurate than colpitts oscillator.
5MHz
If you have an RF (Radio Frequency) signal of 1MHz and you modulate it with a signal of 1kHz you end up with three frequencies 1MHz - 1kHz 1MHz 1MHz + 1kHz The carrier is 1MHz. The lower side band is 1MHz - 1kHz or 999kHz while the upper side band is 1MHz + 1kHz or 1.001MHz kHz is thousand cycles per second MHz is million cycles per second
