What else can I help you with?
When low frequency signals added to high frequency signal then the envelope signal will follow which signal?
the low frequency signal which is nothing but the message signalNeither. The envelope will be that of the difference beat frequency. To get the envelope to follow the low frequency input signal you need to mix (multiply) the two signals, not add them.
What amplifies signals on a network?
It is called an amplifier.
What is VLF as used by the Titantic?
Very Low Frequency radio signals.
A Low Noise Block Down Converter Active or Passive Device?
A Low Noise Block Down Converter (LNB) is an active device. It amplifies the weak signals received from satellite dishes and converts them from a higher frequency to a lower frequency for easier processing. The active components, such as amplifiers and oscillators, are essential for its function, differentiating it from passive devices that do not provide amplification or signal processing.
Which EM waves can carry television signals?
Radio waves. Low frequency.
What is the difference between high frequency signals and low frequency signals in terms of 1 distance that can be traveled 2 transmit power required and 3 susceptability to EMI?
mota
What is a bilinear amplifier?
it amplifies both the incomeing and outgoing signals on CB radios
Can low frequency have a large amplitude?
Yes, low frequency signals can have large amplitudes. Amplitude refers to the strength or intensity of a signal, while frequency refers to the number of cycles of the signal that occur in a given time period. So, a low frequency signal can still have a high amplitude.
What is a statellite dish?
A satellite dish is a parabolic antenna designed to receive signals from satellites orbiting the Earth. It collects and focuses microwave signals onto a receiver, allowing users to access satellite television, internet, or radio services. The dish's shape and orientation are crucial for optimizing signal reception, and it typically includes a low-noise block (LNB) converter that amplifies the incoming signals. Satellite dishes can vary in size and design, depending on their specific application and the frequency of the signals they target.
Give the difference between LPF and HPF?
LPF is a low pass LTI filter which passes the low frequency signals and reduce the amplitude of the signals with frequencies higher than the cutoff frequency. HPF is high pass LTI filter which passes the high frequencies and reduce the amplitude of the frequencies lower than filter's cutoff frequency.
What is the use of oscillators?
Trasmitting stations have their own transmitting frequency. No one can construct an amplifier which amplifies signals over a wide range. So every transmitting frequency has to be changed to one particular frequency. This is known as INTERMEDIATE frequency (IF) This is quite possible by getting beats. So a signal is to generated whose frequency is just more than the incoming frequency by IF This signal is named as local singnal which is generated by the LOCAL oscillator.
What happens at a low frequency?
At low frequencies, sound waves have longer wavelengths and carry less energy. In terms of hearing, low-frequency sounds like a deep bass are perceived as being lower in pitch. In terms of electronics, low-frequency signals are often used for power supply and slower data transmission.
