What is meant by a bandpass signal?
Band pass refers to a specific range of frequencies requires for transmission of a signal over a appreciable distance for effective communication by applying special modulation techniques for effective transmission of a signal.
What is an carrier amplifier?
It is a direct-current amplifier in which the dc input signal is filtered by a low-pass filter, then used to modulate a carrier so it can be amplified conventionally as an alternating-current signal; the amplified dc output is obtained by rectifying and filtering the rectified carrier signal.
How does EZ pass work?
Radio wave signal a transponder.
What are the applications of Butterworth filters?
especially it is very much useful in high quality AUDIO applications because of its flat response in both pass band and stop band where as chebyshev will be useful in signal monitoring applications where the phase is not important criterialow pass filters are used to filter noise from a circuit .noise is a high freequncy signal, when passed through a low pass filter most of the noise is removed and aclear sound is produced
When you pass the digital signal through a transmission medium the output will be a digital signal without any losss?
false
What happens if sampling theory apply to low pass signal?
state and prove sampling theory as applied to low pass signal
What is meant by a bandpass signal?
Band pass refers to a specific range of frequencies requires for transmission of a signal over a appreciable distance for effective communication by applying special modulation techniques for effective transmission of a signal.
Why high pass circuit is called as an Differentiator?
That is its function. An RC low pass circuit is an integrator.
Why low pass filters are required in demodulation process?
Demodulation takes place to extract the low-frequency signal from the high-frequency carrier, using a nonlinear process that produces components at the signal frequency. The LP filter is used to eliminate the high-frequency carrier component from the signal so that it does not cause problems at a later stage in the amplification of the signal.
What different between high pass filter and low pass filter?
A low pass removes frequencies ABOVE a set level. A high pass removes frequencies BELOW a set level. A separate high pass filter can be used to route only frequencies over, say, 80 Hz to your main speakers (if your receiver/processor did not have this function). Then you would set the low pass filter on the subwoofer to 80 Hz to reject signal above that level.
How do you switch from high beam to low beams on 99 ford explorer?
Pull back on the turn signal lever to change from high beams to low beams If the turn signal lever is pushed forward the high beams stay on and if the turn signal lever is pulled back all the way that is the " flash to pass " feature
What is meant by base band digital signal?
It means the signal is not modulated.
Does a low bandwidth signal have more power than a high bandwidth signal?
A low bandwidth signal does not have more power.
What is meant by compartmental pass did he pass or fail?
pass
What is meant by safety and risk?
Risk is the probability of an undesired outcome actually coming to pass. Safety is a condition where the risk is acceptably low.
How ssb operation?
Generate full AM signal. Then pass through very sharp cutoff filter, either high-pass or low-pass, to eliminate carrier and one sideband. At receiver, beat with local oscillator at original carrier frequency.
What is an carrier amplifier?
It is a direct-current amplifier in which the dc input signal is filtered by a low-pass filter, then used to modulate a carrier so it can be amplified conventionally as an alternating-current signal; the amplified dc output is obtained by rectifying and filtering the rectified carrier signal.
