A 65volt neon lamp is connected across a 8h coil with aresistance of 275. When the coil's field collapses, a 6k resisteris inserted into the circuit in series with the coil. The source is 25 volts D.C.A)Calculate the currents flowing as the field builds up atinitial and all five time constants.B)Calculate the voltage developed as the field collapses atinitial and all five time constants.C)Calculate the time range in which the lamp should go out.

1. A signal with a range of 0-12 V is sampled with an 8-bit ADC. What is the change in voltage (delta) between digitized levels 2. Using the SPI, we send three bytes to the LTC2600 DAC. What information is provided in each of the three bytes
Consider a message signal m(t) containing frequency components at 100, 200, and 400 Hz. This signal is applied to a SSB modulator together with a carrier at 100 kHz, with only the upper sideband retained.
Assume the ASCII code is used for each character with an additional parity bit (in the most significant bit position, at left). Each character in ASCII is using 8 bits. Even parity is used. What english word is coded by the following Hexadecimal se..
(a) Determine the cone angle that will match the line to an infinite length biconical antenna. (b) For the cone angle of part (a), determine the two smallest cone lengths that will resonate the antenna.
Design a common-emitter bandpass amplifier having 20dB voltage gain at frequency 1.6 MHz with a bandwidth of 80kHz, when driven by an ideal voltage source and loaded at the output by RL=100k ohm and Rs = 0 ohm.
Common drain amplifier config. uses NMOS device with a nominal load of 2kΩ. If gain of amplifier is 0.90 V/V, what is output resistance. If device has k'n W/L=8mA / V2, what is the bias drain current So need to find Ro and ID.
a)Write the diffrenece equation for a four-term moving average filter. b) The input x[n] = cos(n pi/6)u[n] is passed through the four-term moving average filter. Solve for the first 5 samples of the output.
Any causal signal x(t) having a Laplace transform with poles in the open-left s-plane (i.e., not including the jΩ axis) has, as we saw before, a region of convergence that includes the jΩ axis, and as such its Fourier transform can be found from i..
