An ultra-low power adjustable triangle wave generator with a multi tunable amplitude and frequency is introduced in this paper. The proposed circuit consists of a Schmitt trigger and a current source.

A simplified dynamic model of coal fired power plant is proposed in this paper for the dynamic frequency simulation. The model includes the boiler, pulverizing system and fuel regulation system.

Some people can’t be bothered to read the analog face of a traditional clock. Some people cannot stand the low frequency “hum ...
