Dhansak them the tradition of cooking meat with lentils and/or vegetables. However, tomatoes, chilies, pumpkin and potatoes are native to the Americas and were unknown in India until some time after the Portuguese (who in turn got them through trade with Spain) brought them to India in the 16th century CE. The dhansak is flavoured with a spice mixture called "dhansak masala", which is similar to "garam masala" except that the spices chosen are more aromatic and sweet rather than pungent. Cinnamon, cardamom, cloves, nutmeg, dried ginger, coriander seed and cumin seed, as well as a pinch of asafetida, are among
Pulse-amplitude modulation Pulse-amplitude modulation Pulse-amplitude modulation (PAM), is a form of signal modulation where the message information is encoded in the amplitude of a series of signal pulses. It is an analog pulse modulation scheme in which the amplitudes of a train of carrier pulses are varied according to the sample value of the message signal. Demodulation is performed by detecting the amplitude level of the carrier at every single period. There are two types of pulse amplitude modulation: Pulse-amplitude modulation is widely used in modulating signal transmission of digital data, with non-baseband applications having been largely replaced by pulse-code modulation, and,
