Sambar (dish) sambar are popular for breakfast or an evening snack in the south Indian states. Roadside restaurants often offer free refills of sambar for idli and vadas. Sambar is also served as a side dish for dosa. Sambar (dish) Sambar, also spelled sambhar or sambaar, and pronounced saambaar, is a lentil-based vegetable stew or chowder, originating from the Indian subcontinent, cooked with a tamarind broth. It is popular in South Indian and Sri Lankan cuisines. According to food historian K. T. Achaya, the earliest extant mention of sambar in literature can be dated to the 17th century. Sambar is made either
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
