Development of a receiver circuit for medium frequency

The resulting signal is a binary frequency shift keying (BFSK) signal. It can be easily demodulated with a non-coherent receiver. If phase coherence is maintained at the transmitter, it can also be demodulated (with a smaller probability of error) using a coherent receiver. Both, amplitude shift keying (ASK) and frequency shift keying (FSK) can be extended in a straightforward manner from the

Frequency-shift keying IPFS

An innovative asymmetric binary frequency shift keying (ABFSK) modulation format is presented and studied both in the time domain and frequency domain. First, the modulation function is demonstrated, it shows a quasi-continuous phase attribute and an ability of high speed data modulation. Second, the domain attribute is studied; it has a high degree of energy centralization. Thus, a narrow

Modeling simulation and implementation of a non-coherent

TELE4653 – Lecture 6: Frequency Shift Keying When frequency modulation was studied in analogue systems, we found the analysis to be considerably more complex than that for amplitude modulation, in a large part because FM is a non-linear modulation technique. The same is true in digital systems – the analysis of frequency shift keying is considerably more involved than that of ASK and PSK

FREQUENCY SHIFT KEYING DEMODULATORS FOR LOW-POWER

As its name suggests, a frequency shift keyed transmitter has its frequency shifted by the message. Although there could be more than two frequencies involved in an FSK signal, in this experiment the message will be a binary bit stream, and so only two frequencies will be involved. The word ‘keyed’ suggests that the message is of the ‘on-off’ (mark-space) variety, such as one

While I was writing my book, George C. Williams's (1966) Adaptation and Natural Selection was published. It stressed the individualistic aspect of selection, which was salutary, but was rather simplistic about the hierarchy of individuals. My philosophical work at Harvard was particularly important in allowing me to understand the issues. For it was there that I came to develop the idea that
