What is audio output frequency?
Audio output frequency is that range of frequencies that can be heard. For humans, that is generally considered to be the range of 20Hz to 20kHz.
What is the maximum frequency output can get from 555?
3MHz
What is the effect of low frequency on the voltage?
The frequency would decrease the gain and increase the output voltage
What is the difference between a frequency modulator and a frequency mixer?
A mixer is a non-linear circuit that multiplies two signals together. If the inputs are sinewaves at frequencies f1 and f2 the output will contain signals at four different frequencies, f1, f2, f1 + f2, and f1 - f2. Some mixers may eliminate some of those outputs and post filtering can remove any other unwanted components. This is the way AM and SSB are typically generated. Modulation is a more general concept, and depending on the type of modulation you are doing, a mixer may or may not be involved in the modulation process.
What is a direct coupled amplifier?
Quite simply, it's an amplifier wherein the stages as set up so that the output of one stage is coupled directly into the input of the next stage without any wave shaping or tuninig components between them. This makes for fairly flat frequency response. A link is provided to the Wikipedia article on direct coupling.
What are the frequency determining components in a phase shift oscillator?
The frequency determining components in a phase shift oscillator are the series of resistive/capacitive filters on the output of the inverting amplifier. See accompanying link.
89kHz sinusoidal signal is modulated using an amplitude modulator and a frequency modulator calculate the bandwdith requirement for both modulation schemes?
You can't do this unless you know more detail on the frequency modulator, like its modulation index, for example or the frequency deviation. For the amplitude modulator, it is easy. Bandwidth is twice the signal frequency so in this case the bandwidth is 178kHz for AM.
Why balanced modulator is called balanced modulator?
the output from a balanced modulator consists of modulating freq also. this can be eliminated in a diode modulator by adding two more diodes, making a diode ring. therefore called ring modulator

Which one is an input or output device demodulator and modulator?
An input output device that modulates and demodulates is a modem.
Which modulator can perform amplitude frequency and phase modulation?
ETW-5000
What is the full form of ufm?
ufm = Universal Frequency Modulator / Universal Flow Monitor
What is output frequency of bridge rectifier?
twice the input frequency
Why is your RF modulator not working?
You need to describe symptoms. Check oscillator frequency and power supply.
What is a tank circuit used for?
A tank circuit is used on a radio transmitter. It is an electronic circuit that is used to tune a specific frequency. The tank is made up of two components, an inductor and a capacitor. The two components are connected in a parallel with each other. This is where the term "tank" comes from. Used in a radio transmitter, it is tuned for maximum RF (radio frequency) output on the frequency the transmitter is tuned to.
Is it possible to convert YPbPr output to Coaxial output?
Not generally no. There would be no point. The easiest is to convert the standard yellow video out to coax with an RF modulator
