A Voltmeter, an ammeter (Ampere meter) and a battery cell are connected in series. It is observed that ammeter practically shows No Deflection. Why?
1. Write this as a Boolean expression in canonical minterm form 2. Rewrite the expression in canonical maxterm form 3. Write the complement of f in 'little m' notation and as a canonical minterm expression
Assume that we will use a double-precision number for non-integer numbers (if you recall, this means a binary "scientific notation" with a sign bit, 11 exponent bits using an excess-1024 representation, and a 53-bit mantissa of the form 1.--52 bits-..
A low-voltage lighting system is to use a binary logic control for a particular light. This light lies at the intersection point of a T-shaped hallway. There is a switch for this light at each of the three endpoints of the T.
In designing a low-pass filter for an audio system, the filter stop band attenuation must be at least 40 dB at a frequency that is 2 times the passband frequency. The attenuation in the passband must be less than 1 dB.
An object in a microwave oven 25 cm in diameter and 4 cm thick is being warmed. Determine how deeply the signal penetrates if the objects εr is 12.5 and σ is 2 S/m at a frequency of 2.5 GHz. Assume that the plane wave calculations are valid.
The machine has 180 slotes and has a twolayer winding with 3-turn coil. Each coil spans 15 slotes, the coilbeing connected to 600 groups.The armature diameter is125 c.m. and core length 45 c.m..
Consider a linear circuit with a single voltage source Vs = 1 V and 2000 resistors. The circuit has no other sources. The current through one of the resistors in this circuit is measured to be 5 mA. If the voltage source is changed from 1 V
If we know only the following about a negative feedback system: Gain 12dB, phase 180° at 1rad/sec and gain 0dB, phase 159° at 0.2rad/sec. Determine if system is stable or not.
A voltage source V = 119
Due to saturation effects, the flux at an armaturecurrent of 25A is 45% of that at an armature current of 75A. Findthe motor speed when the armature voltage is 230V and the armature current is 25A.
An enhancement mode MOSFET class AB output stage, The threshold voltage of each transistor is Vtn=-Vtp=1V, and the conduction parameters of the output transistors are Kn1=Kp2=5mA/V^2, Let Ibias=200uA.
The receiver takes the three received bits and decides which bit was sent by taking the majority vote of the three bits. Find the probability that the receiver makes a decoding error.
