What are three main types of shift keying?
The three main types of shift keying are Amplitude Shift Keying (ASK), Frequency Shift Keying (FSK), and Phase Shift Keying (PSK). ASK encodes data by varying the amplitude of the carrier signal, FSK uses different frequencies to represent data bits, and PSK changes the phase of the carrier wave to convey information. Each type has its own advantages and applications in digital communication systems.
Why amplitude shift keyng is called as on offkeying?
Amplitude Shift Keying (ASK) is often referred to as On-Off Keying (OOK) because it represents binary data by switching the amplitude of a carrier signal between two states: a high amplitude (on) for a binary '1' and no amplitude (off) for a binary '0'. This simplicity in representation allows for straightforward modulation and demodulation processes. OOK is a specific form of ASK that directly correlates the presence or absence of signal amplitude to binary values, making it intuitive for digital communication.
What is bpsk circuit?

What is effect on amplitude shift keying modulation and demodulation due to use of transistor SL100?
The SL100 is a PNP medium power transistor, suitable for use up to ~100MHz. This can be used in the power amplifier stage, with the output connected to a tuning network/transformer + antenna for AM modulation. It's purpose, if used in this application, is to supply current (usually a voltage amplifier circuit will precede this one) to drive the antenna.

What is the difference between amlitude shift key and frequency shift key?
Amplitude shift keying changes the height/power of the transmitted signal without altering the frequency. Frequency shift keying changes the frequency of the transmission without altering the height/power of the transmitted signal. Morse code is an example of amplitude keying where the amplitude is 0 or 100%. RTTY teleprinter uses FSK with two frequencies and the codes that represent text characters are sent with patterns of the two frequencies.
Advantages amplitude shift keying?
Amplitude shift keying (ASK) is simple to implement and requires less bandwidth compared to other modulation techniques. It is also less susceptible to noise interference, making it suitable for applications where signal clarity is important. Additionally, ASK is energy efficient as it allows for power conservation by varying amplitude levels.
Advantages and disadvantages of Amplitude Shift Keying?
Information transmission rate is higher. carrier power remain constant

What is QPSK?
QPSK = Quadrature Phase Shift Keying In QPSK amplitude are not much.so the carrier is constant. transmission rate is higher when compared with PSK

Which encoding type easily has a nonzero average amplitude?
Amplitude Shift Keying (ASK) encoding type easily has a nonzero average amplitude because it modulates the amplitude of the carrier signal to represent different symbols. This means that the signal always has a non-zero average amplitude.
