what are the advantages of FM over AM Advantages of FM over AM are 1. It requires less radiated power 2. Low distortion is occurred due to an improved signal-to-noise ratio (about 25dB) with respect to man-made interference. 3. Geographical interference between neighboring stations is smaller. 4. it’s well-defined service areas …Read More »
Advantages and disadvantages of digital communication Advantages 1. due to the advances in digital IC technologies and high-speed computers, digital communication systems are simpler and cheaper compare to analog systems. 2. Regenerative repeaters can be used at a fixed distance along with the link, to identify and regenerate a pulse before it is degraded …Read More »
State sampling theorem The sampling theorem states that a bandlimited signal of finite energy, which has no frequency components higher than W Hz, completely described by specifying the values of the signal at instants of time separated by 1/2𝑊 seconds and, A band-limited signal of finite energy which has no …Read More »
what is slope overload distortion and granular noise Slope overload distortion When the input signal is rising or falling with a slope larger than 𝛿/𝑇𝑠; where 𝛿 is the size of the individual steps and 𝑇𝑠 is the sampling period, we say that the sampler is suffering from Slop Overload …Read More »
Amplitude modulation math Example Suppose we have carrier frequency ω = 2π× 10^5rad/sec; Find the frequency component of Amplitude Modulated (AM) signal s(t) of the message signal is given below:(a) m(t) = A0cos(2π× 103t)(b) m(t) = A0cos(2π× 103t) + A0cos(4π× 103t)(c) m(t) = A0cos(2π× 103t) sin(4π× 103t)(d) m(t) = A0cos2(2π× …Read More »
Baseband Signal Cannot Be Transmitted Through Space By Radio The message signal that is to be transmitted is referred to as „baseband signal‟. In a communication system, when the original information signals (baseband signals) may be transmitted over the medium directly, it is referred to as “baseband transmission”. One example …Read More »
What Are The Basic Components Of Communication System? Draw And Explain The Block Diagram Of The Typical Communication System?
Basic Components Of Communication System The elements of the communication system are as follows: i) Information ii) Transmitter iii) A channel or medium iv) Noise v) Receiver Information: The communication system communicates messages. The messages come from information sources. it’s going to contain human voice, picture, code, data, music, and their combination. Transmitter: …Read More »
