A variable-frequency voltage source of value 12cos(wt) drives a network with a resistor of value 12 ohms, an inductor of value 50mH, and a capacitor of value 5uF, all in series, in that order. Determine the resonant frequency, Q, bandwitdh, and the average power dissipated by the network at resonance.
A circuit designer requires a gain of 25 (+or -) 1% V/V using an amplifier whose gain varies by a factor of 10 over temperature and time. What is the lowest gain required. The nominal gain. The value of B(beta).
