Question

A communications link uses M’ary FSK modulation where each symbol can be represented by eight different frequencies (f1, f2, f3, f4, f5, f6, f7, f8). How many bits can be represented by each symbol? a. 1 bits per symbol b. 2 bits per symbol c. 3 bits per symbol d. 4 bits per symbol According to Hartley’s Law, data rate increases as M (number of levels per symbol) increases. True False CODECs (coder – decoders) are devices used to convert analog signals to digital signals (A-D), and digital signals to analog signals (D-A). True False

Explanation / Answer

3ans) TRUE

the term CODEC stands for COder/DECoder Associate in Nursingd is largely an analog-digital converter (ADC) and a data converter (DAC) in one package. A codec, whether or not hardware or emulated in computer code, converts analog audio signals into digital signals for transmission or encodes them for storage during a digital format. Later, the decoder facet of a codec will be wont to decompress Associate in Nursingd convert the digital knowledge into an analog signal. Associate in Nursing example of a tool with a codec may be a recording/playback device. CODECs ar accountable for ever-changing the sound that a mike picks up and changing it to a stream of 0s and 1s for transmission (analog-to-digital conversion), or during a a lot of common vernacular, “data streaming“ if the digital signal is transmitted. codecs also are used for encryption, press, decoding, and pressure video similarly.
