Amplitude Shift Keying A S K is a type of Amplitude Modulation which represents the binary data in the form of variations in the amplitude of a signal. Any modulated signal has a high frequency carrier. The binary signal when ASK modulated, gives a zero value for Low input while it gives the carrier output for High input. The output of IC1A is FSK, as the site promises, but also works for ASK (at least for the values I have for the R’s, C’s, L’s, etc). We need to do an additional amount of processing to obtain the PSK though. Since I have a baseline of 2.5V and a high of 3.6V and a low of 0V, I’ll try gating each high and low with a separate comparator. ASK, PSK and FSK are signaling schemes used to transmit binary sequences through free space. In these schemes, bit-by-bit transmission through free space occurs. FSK (Frequency Shift Keying): In FSK (Frequency Shift Keying) binary 1 is represented with a high-frequency carrier signal and binary 0 is represented with a low-frequency carrier, i.e. This page on ASK vs. PSK provides difference between ASK, FSK, PSK modulation types. All these are digital modulation techniques. Unlike Analog modulation, here input is in digital binary form. The other input is the RF carrier. Input binary data is referred as modulating signal and output is referred as modulated signal.

- Ask Fsk Psk Are Examples Of Which Conversion
Quite often we have to send digital data through analog transmission media such as a telephone network. In such situations it is essential to convert digital data to analog signal.
Basic approach is shown in Figure below. This conversion is accomplished with the help of special devices such as modem (modulator-demodulator) that converts digital data to analog signal and vice versa.
ASK, FSK, and PSK with Neat Diagram
Digital to Analog conversion
Digital data needs to be carried on an analog signal.
A carrier signal (frequency fc) performs the function of transporting the digital data in an analog waveform.
Amplitude Shift Keying (ASK)
ASK is implemented by changing the amplitude of a carrier signal to reflect amplitude levels in the digital signal.
For example: a digital could not affect the signal, whereas a digital would, by making it zero.
Frequency Shift Keying(FSK)
The two binary values are represented by two different frequencies
