Direct sequence contrasts with the other spread spectrum process, known as frequency hopping spread spectrum, or frequency hopping code division multiple access (FH-CDMA), in which a broad slice of the bandwidth spectrum is divided into many possible broadcast frequencies.
Puppies are generally ready to eat solid food between the ages of 6 to 8 weeks old. However, according to Purina, it's not uncommon for puppies to start eating from their mother's dish at 4 or 5 weeks old. A puppy attempting to eat adult food does not necessarily mean it's ready to be weaned. The Complete Book of Dog Breeding warns owners that an aggressive appetite is only one sign of maturity.
Puppies should be eating food labeled for growth or for all life stages. After a month or six weeks on the food, assess your puppyâs health. He should be playful and energetic, with a shiny, thick coat. Formed brown feces are a sign that your puppy is digesting most of the nutrients in the food. Puppies should eat three times a day from weaning through four to six months, if possible. After six months, twice-a-day feedings are fine. But if youâre not able to feed your pup three times a day, donât worry. Buffington says puppies can adapt.
