Q. Consider the 4-bit R-2R ladder D/A converter with Vref =-10 V. Determine the analog output voltage when the binary input code is 1100. Also, find what reference voltage is to be used in order to obtain the corresponding decimal output voltage.
Suppose we have a coil wound onto a ring of material with relative permeability µ r . Provided that the relative permeability µ r >> 1, then the magnetic flux lines will s
Definition of Magnetism Magnetism is explained as the force produced by charge particles (electrons) of magnet. A magnet is a material that obtained a magnetic field.

Q. (a) The concept of duality can be extended to nonelectric physical systems bymeans of analogs. For example, the mechanical system characteristics can be investigated by means
Limitations: 1. Silicon transistors do not function at voltages much higher than about 1,000 volts (SiC devices can be worked as high as 3,000 volts). In difference, electron
Let a message signal m(t) have a bandwidth of 10 kHz and a peak magnitude of 1 V. Estimate the bandwidth, by using Carson's rule, of the signal u(t) obtained when m(t) modulates a
