depends on type of modulation and other variables
In Analog communication, the analog message signal modulates some high carrier frequency inside the transmitter to produce modulated signal.this modulated signal is then transmitted with the help of a transmitting antenna to travel through the transmission channel. At the receiver, this modulated signal is received and processed to recover the original message signal. Example: AM , FM radio transmission an TV transmission. In digital communication, the message signal to be transmitted is digital in nature. This means that digital communication involves the transmission information in digital form Example: ASK, FSK, PSK.
in general the CE amplifiers are called low-signal amplifiers as they use only small values of voltage as a source of input which cant be used in practical purposes, whereas power amplifiers deal with practical values of input and output voltages
Image signal is a multidimensional signal with respect to both independent (spatial) and dependent (intensity) variables.
if a signal is a function of single independent variable,then signal is called multichannel signal. if a signal is function of multiple independent variable then signal is called multidimensional signal.
A multichannel signal refers to a signal that consists of multiple individual channels, each representing a different aspect or component of the overall signal. These channels can be used to convey different types of information simultaneously. On the other hand, a multidimensional signal refers to a signal that has multiple dimensions, with each dimension representing a different characteristic or parameter of the signal. This can include signals that vary in multiple dimensions such as time, frequency, spatial location, or any other relevant parameter.
the first practical radio signal system is Jan Hendrix Campos
In the Narrow-band channel the signal see the channel as a flat channel , and the signal pass the channel without any type of cut . In the other hand the signal that passes through the wide-band channel see the channel as a frequency selective channel and cut values from the signal . I mean that if the bandwidth for the signal is lager than the bandwidth for the channel then, the channel is a wide-band channel, and if the bandwidth for the signal is smaller than the bandwidth for the channel then the channel will be a narrow-band channel .
There is no frequency of mono. Mono is a one channel signal, stereo is a two channel signal.
Yes, if you tune the microphone to for example channel 2, and both of the receivers to channel 2 also, you will be able to get the signal on both receivers.

Calculate the capacity of a telephone channel of 3000hz and signal to noise ratio of 3162?
Yes, this is a true statement. A TV channel is most often characterized by the frequency of its transmitted signal.
