A given low pass filter has a cutoff frequency fc and a sample frequency fs. The sampling period is T = 1/fs. In implementing the filter it is essential that the evaluation of the difference equation be completed in less than T seconds. What are the consequences with regard to fc if this is not the case. For example, suppose it takes 1.2T to do the evaluation of the difference equation.
In other words, your approach should be able to answer the question whether two BDDs are complements of each other, without using the complement operation.
A three-phase transmission line having a reactance of 120 ohms per phase is connected to a wye-connected load whose resistance is 160 ohms per phase. If the supply volatge is 70kV line-to-line, calculate a) The line-to-neutral voltage per phase.
An LVDT (Linear Variable Differential Transformer) is used in an accelerometer to measure seismic-mass displacement. The LVDT and signal-conditioning output is 0.31 mV/mm with a +/- 2 cm maximum core displacement.

An OpAMP has a unity gain frequency (ft) of 10MHz and a slew rate of 10V/us and AVoc = 120dB at DC (f=0). Assume VCC = -VEE = 15 Volts.a. Approximate the cutoff frequency of the OPAMP itself. b.
Explain why the short-circuit method for determining the Thevenin resistance of a circuit cannot be applied if the circuit does not contain any independent current or voltage sources.
Design a circuit with minimum number of gates for a binary multiplier that multiplies two unsigned four-bit numbers, Using Inverters, AND, OR gates and Full Adders.
the upper critical frequency of anop-amps open loop response is 200Hz. If the midrange gain is 175,00, what is the ideal gain at 200Hz? what is th actual gain? what is the op-amps open loop bandwidth?
A signal x[n] is formed by sampling a signal x(t) = -4sin(200*pi*t) at a sampling rate of 400Hz. Graph x[n] over 10 fundamental periods versus discrete time. Then do the same for the sampling frequencies of 60 and 200Hz.
