WHAT IS Matlab code for constellation diagram for fsk modulation?
To create a constellation diagram for Frequency Shift Keying (FSK) modulation in MATLAB, you can use the following code snippet: % Parameters fs = 1000; % Sampling frequency T = 1; % Duration of the signal t = 0:1/fs:T-1/fs; % Time vector f1 = 1; % Frequency for '0' f2 = 2; % Frequency for '1' % FSK signal generation data = [0 1 0 1]; % Example binary data signal = []; for bit = data if bit == 0 signal = [signal sin(2*pi*f1*t)]; else signal = [signal sin(2*pi*f2*t)]; end end % Constellation diagram scatter(real(signal), imag(signal)); title('Constellation Diagram for FSK Modulation'); xlabel('In-Phase'); ylabel('Quadrature'); grid on; This code generates an FSK signal based on the binary input data and then plots the constellation points in a scatter plot. Adjust the parameters as needed for your specific requirements.
How is it possible to represent a complex exponential signal with a frequency of 20Hz using a sampling frequency of 30Hz?
A 20Hz signal must be sampled at a minimum of 40Hz to have a chance of sampling both peaks and to get a reasonable representation it must be sampled at a minimum of 100Hz.For a sampling rate of 30Hz the Nyquist frequency is 15Hz and since 20Hz is above that it will generate the alias signal of 10Hz in the sampled data instead of the original signal of 20Hz. Therefore it is not possible to do what you ask.
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 is difference between oscillator and regulator ic?
oscillator is which oscillates to a required proportion in order to generate signal with required frequency. whereas, regulator limits the signal to a predefined value and offers a constant out put through out
Is The carrier frequency is usually lower than the modulating frequency?
when the frequency is low , energy will be obviously low. To increase the energy of the signal we need to increase the frequency. This is achieved by multiplying the message signal with the carrier signal (with high frequency).
Why used a clock signal timing diagram?
We use clock signal in timing diagram because the microprocessor operates with reference to clock signals provided to it. At pins X1 and X2 we provide clock signals and this frequency is divided by two. This frequency is called as the operating frequency.
What is function of an oscillator?
A local oscillator is an electronic device used to generate a signal normally for the purpose of converting a signal of interest to a different frequency using a mixer. This process of frequency conversion, also referred to as heterodyning, produces the sum and difference frequencies of the frequency of the local oscillator and frequency of the input signal of interest. These are the beat frequencies. Normally the beat frequency is associated with the lower sideband, the difference between the two.
Does a signal generator generate sound waves?
A signal generator produces electrical signals that can be converted into sound waves by speakers or other devices. The generated signal can vary in frequency, amplitude, and shape to create different types of sound waves.
Why 2 mixers in VHF diagram?
In a VHF (Very High Frequency) diagram, two mixers are typically used for frequency conversion to improve performance and selectivity. The first mixer down-converts the incoming VHF signal to an intermediate frequency (IF), allowing for better filtering and amplification. The second mixer can be utilized for further processing or to shift the signal to a different frequency band. This dual-mixer setup enhances the overall system's sensitivity and dynamic range, enabling more effective signal processing in communication systems.

What is the significance of transfer function of a system?
It tells you what the system does to the input signal(s) to generate the output signal(s). The transfer function can be expressed in either the time domain or the frequency domain, depending on whichever is easier to deal with in the application.
Comparison of amplitude modulation and frequency modulation?
Amplitude of the (high frequency) Carrier signal is varied with respect to low frequency of message signal is called amplitude modulation. Frequency of the carrier signal is varied with respect to low frequency of message signal is called frequency modulation.

What signal has wider bandwidth sine wave with frequency 100HZor 200HZ?
The signal with a frequency of 200Hz has a wider bandwidth compared to a signal with a frequency of 100Hz. Bandwidth is determined by the range of frequencies present in a signal, so a higher-frequency signal will have more frequency components and thus a wider bandwidth.
Why you convert FM signal to IF frequency?
Mix it with a local oscillator whose frequency is (the IF frequency) away from the frequency of the FM signal you're interested in.
What is difference between oscillator and regulator ic?
oscillator is which oscillates to a required proportion in order to generate signal with required frequency. whereas, regulator limits the signal to a predefined value and offers a constant out put through out
