Practically, there are some factors that affect the frequency stability of Variation in temperature Oscillator
• Circuit Components
- Values of R, L and C changes with temperature
• Transistor Parameters
- causes variation in transistor parameters
• Supply Voltages
- Variations in power supply
• Stray Capacitances
• Output Load
- Variations of load causes a change in effective resistance
• Inter‐element Capacitance

Why you use crystal oscillator in 8085 microprocessor?
The oscillator provides the basic clock of a microcontroller to be able to execute the instructions in a stable, periodic way. It is often used for other peripherals too, like timer, UART, etc. as frequency base, usually divided by a clock divider for integer factors, or by PLL for rational factors. If the timing accuracy of these functions is not important, a simple RC oscillator can be used. Many microcontrollers have it internally. Accuracy is in 1...10% range. For better accuracy and temperature stability, a resonator can be used. For applications where timing is critical, a crystal can be used. Most micros have built-in oscillator, so only a crystal and two caps are needed. For those which have no built-in oscillator, external crystal oscillator module may be used. There are OCXO and TCXO modules available for very high stability needs.
Is amplitude a measure of a waves energy?
Not exactly. The amplitude of a mechanical wave means how much the particles move from their resting position. The amplitude of an electrical wave specificies how much the voltage or current varies, etc. The amount of energy for a specific wave does depend on the amplitude - more amplitude means more energy. However, the energy also depends on other factors.
Which factors affect loudness?
Loudness is the quality of a sound that is the primary psychological correlate of physical strength or amplitude. It is a subjective felt impression and is often confused with objective measure of sound pressure.
What are two factors that affect sound quality?
Speed of Sound and frequency
What are the factors that affect the period of a pendulum?
In an ideal pendulum, the only factors that affect the period of a pendulum are its length and the acceleration due to gravity. The latter, although often taken to be constant, can vary by as much as 5% between sites. In a real pendulum, the amplitude will also have an effect; but if the amplitude is relatively small, this can safely be ignored.
What factors affect the pitch?
Loudness, pitch and timbre are approximately the correlates of signal amplitude, frequency and frequency spectrum, respectively.
What factors determines the loudness of sound?
Frequency of the sound wave ?Amplitude of the sound wave ?The temperature of the medium ?The density of the medium ?
What are the factors affect the pitch of sound?
okay whoever said that mass affected pitch is just stupid.... Frequency and amplitude affect pitch

What factors effect the loudness of sound?
Loudness effects the following factors 1.frequency 2. Amplitude 3. Distance of listener. 4 direction of wind thanks for watching by farida rehman ........
Why microprocessor frequency is half of crystal frequency?
The crystal oscillator frequency in the Intel 8085 is divided by 2 because Intel designed it that way. Internal actions in the 8085 occur at various points in the cycle and, by dividing by 2, Intel could create 4 distinct points in the cycle where various edges could perform actions.
Factors that affect pitch and sound?
The amplitude of the sound wave, and how close the listener is to the source of the sound. The lower the amplitude, the lower the intensity. The further away a person in, the lower the perceived intensity.
What does modulation mean in signal processing?
In signal processing, modulation means altering the wave form in some manner. This could include altering one of the three factors of a wave form. These are the amplitude, frequency, and phase.
What are the determining factors in a ships seaworthiness?
stability
Factors responsible for stability of quiescent point?
Biasing of the transistor is responsible for stability of Q point.
What is the standard frequency and on which factors does it depend on?
standard frequency in India is 50Hz
What are the factors that affect the bias stability of a transistor?
temperature
