- Q1. What is frequencyand explain it ?
- Ans.
Frequency is the number of cycles per second in a periodic waveform.
Frequency is measured in Hertz (Hz).
It determines the pitch of a sound wave.
Higher frequency means higher pitch and vice versa.
Frequency is used in various fields like electronics, physics, and communication.
Example: The frequency of a radio station is 98.5 MHz.
- Q2. What is wavelength and explain it?
- Ans.
Wavelength is the distance between two consecutive peaks or troughs of a wave.
Wavelength is measured in meters or nanometers.
It determines the color of light and sound frequency.
Shorter wavelengths have higher energy than longer wavelengths.
Examples include the wavelength of visible light, radio waves, and X-rays.
- Q3. Relationship between wavelength and frequency
- Ans.
Wavelength and frequency are inversely proportional to each other.
Wavelength is the distance between two consecutive peaks or troughs of a wave.
Frequency is the number of waves passing through a point in one second.
The higher the frequency, the shorter the wavelength.
The lower the frequency, the longer the wavelength.
The relationship between wavelength and frequency is described by the equation: wavelength = speed of l...
- Q4. What is pulse code modulation
- Ans.
Pulse code modulation is a digital representation of analog signals.
PCM is used to convert analog signals into digital signals.
It involves sampling the analog signal at regular intervals and quantizing the amplitude of each sample.
The resulting digital signal can be transmitted or stored more efficiently than the original analog signal.
PCM is commonly used in audio and video recording and transmission.
It is also used i

- Q3. What are the types of modulations?
- Ans.
Modulation is the process of varying a carrier signal in order to transmit information.
Amplitude Modulation (AM) - varying the amplitude of the carrier signal
Frequency Modulation (FM) - varying the frequency of the carrier signal
Phase Modulation (PM) - varying the phase of the carrier signal
Quadrature Amplitude Modulation (QAM) - combining amplitude and phase modulation
Pulse Amplitude Modulation (PAM) - varying the amp...
- Q4. What is the difference between 2G, 3G, 4G? Why 5G?
- Ans.
2G, 3G, 4G, and 5G are different generations of mobile network technology.
2G refers to second-generation mobile networks that primarily provided voice and text messaging services.
3G introduced faster data transfer speeds, enabling internet browsing, video calling, and multimedia services.
4G further improved data speeds, offering high-quality video streaming, online gaming, and advanced mobile applications.
