How to Generate digital data for bpsk modulation?
Which modulation technique is used in gsm?
GSM uses GMSK modulation scheme. GPRS also uses GMSK modulation scheme. EDGE and UMTS uses 8-PSK.
Which modulation scheme requires the least minimum bandwidth?
Suppressed carrier single sideband amplitude modulation - SCSSBAM.
What is the most commonly used quadrature amplitude modulation?
The most commonly used quadrature amplitude modulation (QAM) is 16-QAM. It combines amplitude and phase modulation to transmit data efficiently by encoding four bits per symbol, represented by 16 different signal points on a constellation diagram. This modulation scheme balances bandwidth efficiency and robustness against noise, making it widely used in digital communication systems, including Wi-Fi and digital television.
Which pulse modulation scheme is used as an intermediate step in the creation of PCM?
The pulse amplitude modulation (PAM) scheme is used as an intermediate step in the creation of pulse code modulation (PCM). In PAM, the amplitude of discrete pulses represents the sampled values of the analog signal. These amplitude levels are then quantized and encoded into a binary format to produce the final PCM signal. This process enables the efficient digital representation of analog information for transmission and storage.
Which analog modulation scheme requires minimum transmitted power and minimum channel bandwidth?
ssb modulation scheme
Advantages of hybrid modulation over digital modulation?
presentation of analog digital hybrid modulation
Need of demodulation?
Demodulation is needed with modulation becoz modulation it is converting analog to digital signal n we can't understand digital. That's why we require digital to analog converter or demodulator.
What are the advantages of digital modulation over analog modulation?
1)digital modulation can easily detect and correct the noise. where as analog modulation has little complexity 2)security is more in digital modulation 3)digital modulated signal can traverse a long distance compared to analog modulation

What is the difference between analog and digital modulation Does it depends on baseband signal?
The basic difference is that in analog modulation the modulating signal is analog signal and in digital modulation it is in digital form.
What were the bell 101 modulation frequencies?
The Bell 101, an early experimental digital communication system developed by Bell Labs, utilized modulation frequencies of 1, 2, and 3 kHz. These frequencies were employed to encode digital information into audio tones, allowing for the transmission of data over telephone lines. This modulation scheme was part of the early advancements in digital communication technology, paving the way for future developments in data transmission.

What is the unit for modulation index?
Modulation index is also called as Modulation depth. The modulation index of a modulation scheme describes by how much the modulated variable of the carrier signal varies around its unmodulated level.
