Why the linear combination of a low frequency intelligence signal and a high frequency carrier signal is not effective as a radio transmission?
to shift the frequency of information signal ,at the frequency domain to a higher frequency ...so the information can be transmitted to the receiver.
Relation between transmitted power and range?
usually more power means more range. Now frequency come into play and obstacles to the transmission. there is no definite answer
What is the relationship between frequency and bandwidth in terms of data transmission?
Frequency and bandwidth are closely related in data transmission. Frequency refers to the number of cycles per second that a signal oscillates at, while bandwidth is the range of frequencies that a signal occupies. In data transmission, higher frequencies allow for more data to be transmitted in a given amount of time, resulting in a wider bandwidth. Therefore, a higher frequency signal typically has a larger bandwidth and can carry more information.
Is it right that a television channel is characterized by frequency of transmitted signal?
Yes, this is a true statement. A TV channel is most often characterized by the frequency of its transmitted signal.
Would the linear combination of a low frequency intelligence signal and a high frequency carrier signal be effective as a radio transmission?
Yes, a linear combination of a low-frequency intelligence signal and a high-frequency carrier signal can be effective for radio transmission. This method, known as amplitude modulation (AM) or frequency modulation (FM), allows the low-frequency signal to be transmitted over longer distances by utilizing the high-frequency carrier wave. The carrier wave effectively "carries" the information, enabling it to be received and demodulated by appropriate receivers. This technique is fundamental in broadcasting and communication systems.
What is the difference between amlitude shift key and frequency shift key?
Amplitude shift keying changes the height/power of the transmitted signal without altering the frequency. Frequency shift keying changes the frequency of the transmission without altering the height/power of the transmitted signal. Morse code is an example of amplitude keying where the amplitude is 0 or 100%. RTTY teleprinter uses FSK with two frequencies and the codes that represent text characters are sent with patterns of the two frequencies.
Is FDM is an example of parallel transmission?
Frequency Division Multiplexing (FDM) is not an example of parallel transmission; rather, it is a method of multiplexing that allows multiple signals to be transmitted simultaneously over a single communication channel by assigning each signal a different frequency. In FDM, each signal occupies a unique frequency band within the overall bandwidth, enabling concurrent transmission without interference. Parallel transmission, on the other hand, involves sending multiple bits simultaneously over multiple channels or wires.
What is a sentence for transmitted?
We have transmitted the signal.She transmitted the disease to her lover.
What is the adjective form of Transmission?
Transmissible
Can harmonics be transmitted through a frequency converter?
Well, sort of. Harmonics are a sound property that will be modified along with the frequency when passed through a frequency converter. Yes, it is possible for harmonics to be transmitted through a frequency converter. You just need to double check to make sure the frequency converter is capable of doing the task
Are gsm use sfh to improve signal?
Frequency Hopping is an old technique introduced firstly in military transmission system to ensure the secrecy of communications and combat jamming. Frequency Hopping is mechanism in which the system changes the frequency (uplink and downlink) during transmission at regular intervals. It allows the RF channel used for signaling channel (SDCCH) timeslot or traffic channel (TCH) timeslots, to change frequency every TDMA frame (4.615 ms). The frequency is changed on a per burst basis, which means that all the bits in a burst are transmitted in the same frequency.
What is base band frequency?
Baseband frequency refers to the range of frequencies over which a signal is transmitted without modulation. In communication systems, baseband signals typically occupy the frequency range from 0 Hz to the upper limit of the signal bandwidth. This is in contrast to passband signals, which are modulated onto carrier frequencies for transmission over a channel.
