Sambar (dish) powder. In Andhra Pradesh, it is called as "Pappu chaaru". Apart from dal and tamarind, vegetables used in preparing is few. Vegetables are onions, dosakaaya, bitter gourd and tomatoes. Sambar without lentils (but with vegetables, or dried or fresh fish) is called kuzhambu in Tamil Nadu. Sambar is usually served with steamed rice as one of the main courses of both formal and everyday south Indian cuisine. A two-course meal of sambar mixed with rice and eaten with some sort of vegetable side dish, followed by yoghurt mixed with rice, is a prime southern Indian staple. "Vada" sambar and "idli"
Pulse compression The SNR is proportional to pulse duration formula_30, if other parameters are held constant. This introduces a tradeoff: increasing formula_30 improves the SNR, but reduces the resolution, and vice versa. How can one have a large enough pulse (to still have a good SNR at the receiver) without poor resolution? This is where pulse compression enters the picture. The basic principle is the following: In radar or sonar applications, linear chirps are the most typically used signals to achieve pulse compression. The pulse being of finite length, the amplitude is a rectangle function. If the transmitted signal has a duration
